BACKGROUND OF THE INVENTION

Existing systems and methods for clinical testing suffer many drawbacks from the perspectives of patients, health care professionals, and taxpayers or insurance companies. Today, consumers can purchase certain specialized tests from various locations for consumer use. For example, a consumer can purchase a pregnancy test at a pharmacy and review the results. However, such results are to be viewed by the consumer, and are not to be relied on by the consumer's physician in forming a screening, diagnosis or treatment plan.

Additionally, if a test result is to be conducted and to be relied on by a doctor, physical samples are transported to a laboratory where the tests on the samples are performed. For example, blood from a fingerstick or venous draw is typically collected from a subject at a hospital or physician's office. The blood sample is shipped to a Clinical Laboratory Improvement Amendments (CLIA) certified laboratory which performs the tests and analysis that is provided to the patient's doctor. Such techniques are cumbersome and cause significant delay in providing the result of a test ordered by a physician, especially because the physical specimens must be transported to a different site for analysis. Moreover, the sample collection sites often have limited hours which further causes inconvenience to patients.

Conventional techniques are also problematic for certain diagnoses. Some tests are time sensitive, and the results of which may take days or weeks to complete. In such a time, a disease can progress past the point of treatment. This impairs a medical professional's ability to provide quality care.

Traditional systems and methods also affect the integrity and quality of a clinical test due to degradation of a sample that often occurs while transporting such sample from the site of collection to the place where actual analysis of the sample is performed. For examples, analytes decay at a certain rate, and the time delay for analysis can result in loss of the sample integrity. Different laboratories also work with different qualities which can result in varying degrees of error. Each laboratory can have its own set of references that further introduce a wide range of variability in coefficients of variation. Additionally, preparation of samples by hand permit upfront human error to occur from various sample collection sites. These and other drawbacks inherent in the conventional setup make it difficult to perform longitudinal analysis with high quality.

Furthermore, the conventional techniques are typically not very cost effective. For example, delays in test results lead to delays in diagnoses and treatments that can have a deleterious effect on a patient's health. For example, a disease may progress further, resulting in the patient needing additional treatment. Payers, such as health insurance companies and taxpayers contributing to governmental health programs, end up paying more to treat problems that could have been averted with more accessible and faster clinical test results.

SUMMARY

A need exists for improved systems and methods that allow higher quality of care, more rapid and accurate screening, diagnosis and/or treatment. Specifically, there is a considerable need for sample collection, preparation and analysis. A further need exists for easily accessible sample collection sites, while permitting the analysis of data that can be relied on by a health care professional.

Systems and methods are further needed for earlier intervention and providing high quality of care with little variability and reduced human error to enable the performance of longitudinal analysis of data. Systems and methods disclosed herein meet this need and provide related advantages as well.

DETAILED DESCRIPTION

While preferable embodiments of the invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions will now occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed in practicing the invention.

The invention provides systems and methods for collecting and transmitting data relating to a sample, and often representative of the sample so that further analysis of the sample does not require physical transportation of the sample. Various aspects of the invention described herein may be applied to any of the particular applications set forth below or for any other types of diagnostic or assay systems. The invention may be applied as a standalone system or method, or as part of an integrated system, such as in a system between laboratories, health care professionals, and sample collection sites. It shall be understood that different aspects of the invention can be appreciated individually, collectively, or in combination with each other.

It must be noted that, as used in the specification and the appended claims, the singular forms “a”, “an”, and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a reagent” refers to a single reagent and to multiple reagents, and reference to “an assay” refers to a single assay and to multiple assays.

As used in the description herein and throughout the claims that follow, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise.

As used in the description herein and throughout the claims that follow, the meaning of “or” includes both the conjunctive and disjunctive unless the context expressly dictates otherwise. Thus, the term “or” includes “and/or” unless the context expressly dictates otherwise.

As used in the description herein, the term “embodiments” and the phrase “in embodiments” and linguistic variants thereof refer to exemplary features, elements, capabilities, and combinations thereof, of devices, systems, and methods as disclosed herein. Disclosure of a particular feature, or element, or capability, or particular combination of features, elements, or capabilities, is not limiting, but are illustrative of such, and may include other combinations and other aspects of such features, elements, and capabilities.

In this specification and in the claims that follow, reference will be made to a number of terms, which shall be defined to have the following meanings:

The term “analyte” and its plural and other forms, as used herein, includes without limitation drugs, prodrugs, pharmaceutical agents, drug metabolites, biomarkers such as expressed proteins and cell markers, antibodies, antigens, proteins, hormones, polypeptides, glycoproteins, polysaccharides, lipids, viruses, cholesterol, polysaccharides, nucleic acids, genes, nucleic acids, and combinations thereof.

As used herein, the term “cell count” refers to a qualitative or quantitative assessment of the number of cells in a sample, or in a volume, or in a field of view, or on a surface. An estimate of the number of cells in a sample, e.g., by absorbance of light passing through, or scattered or otherwise altered by cells in a sample; by light or other radiation emitted by cells expressing fluorescent or otherwise detectable proteins, or labeled by dyes, radionuclides, or other markers; an enumeration of the number of cells in an image (e.g., an image of a blood or urine sample, a tissue slice, or other biological sample, acquired by a camera, a microscope, or other optical imaging device), and a quantitative measurement of the number of cells adherent to a surface are all examples of a cell count.

As used herein, the term “cytometry” refers to observations, analysis, methods, and results regarding cells of a biological sample, where the cells are substantially at rest in a fluid or on a substrate. Cells detected and analysed by cytometry may be detected and measured by any optical, electrical or acoustic detector. Cytometry may include preparing and analyzing images of cells in or from a biological sample (e.g., two-dimensional images). The cells may be labeled (e.g., with fluorescent, chemiluminescent, enzymatic, or other labels) and plated (e.g., allowed to settle on a substrate) and detected. Cells may be, for example, imaged by a camera. A microscope may be used for cell imaging in cytometry; for example, cells may be imaged by a camera and a microscope, e.g., by a camera forming an image using a microscope. An image formed by, and used for, cytometry typically includes more than one cell. As used herein, the term “cytometry” refers to measurements made without substantial cell motion with respect to the device (e.g., the cells are observed and imaged while at rest with respect to a surface of the device). In this regard, the term “cytometry” as used herein is different from, and refers to different observations, analysis, methods, and results than are referred to by the more limited term “flow cytometry.”

As used herein, the term “flow cytometry” refers to observations and analysis of cells, where the cells are in motion within a device, or with respect to a surface of a device. Flow cytometry typically uses a mobile liquid medium that sequentially carries individual cells to an optical, electrical or acoustic detector; e.g., in a typical flow cytometer, cells are carried by a moving fluid past a stationary detector.

As used herein, the term “microscopy” refers to the use of magnifying lenses and other optical methods to provide an image of a target, such as a cell or a plurality of cells. Microscopy typically uses optical or acoustic means to detect stationary cells, generally by recording at least one magnified image. An image formed by microscopy typically provides greater resolution than is possible when viewing the target by eye alone; for example, the image may be enlarged. Optical methods and techniques used in microscopy, in addition to the use of lenses for refraction, include the use of mirrors, prisms, filters, polarizers, gratings, grids, light sources, scanning methods and techniques (e.g., as used in confocal microscopy), special apertures (e.g., a pin-hole), and other methods.

As used herein, “spectroscopy” refers to assays and measurements using light intensity, including light intensity as a function of light wavelength to detect and assess a sample. Spectoscopy includes measurements of the reflection or transmission of electromagnetic waves, including visible, UV, and infrared light. Spectroscopy includes any and all assays that produce luminescence or change light (e.g., color chemistry). These may include one or more of the following: spectrophotometry, fluorimetry, luminometry, turbidimetry, nephelometry, refractometry, polarimetry, and measurement of agglutination.

The term “fluorimetry” as used herein refers to measuring the light emitted by a fluorescent molecule coupled to a subject upon exciting the fluorescent molecule with incident light.

As used herein, “luminometry” refers to measurements and observations that use no external illumination method, but instead detects electromagnetic radiation emitted by or from the object, chemical reaction, or area of interest. The emitted light may be weak, and thus luminometry may require the detection of low light or other radiation levels; such signals can be detected using an extremely sensitive sensor such as a photomultiplier tube (PMT). Luminometry includes assays that produce chemiluminescence, such as those using luciferases or some assays using peroxidases.

As used herein, “turbidimetry” refers to detection, measurement, or observation of a sample or reaction in a sample by backlighting the sample and components within the sample with white light, with the result being sensed by an imaging sensor. The reduction of the intensity of the transmitted light is measured (the intensity of the incident light being known). Turbidimetry may be used, for example, to determine a concentration of cells in solution. In some embodiments, turbimetry is measured by nephelometry.

As used herein, the term “nephelometry” refers to measurements of light that is transmitted or scattered after passing through a suspension, e.g., a suspension of target analytes in a solution. For example, the amount of a substrate bound to an immunoglobin such as IgM, IgG, and IgA may be measured by nephelometry.

As used herein, the term “polarimetry” refers to measurements of the polarization of light or other electromagnetic radiation following reflection, refraction, or other contact with subject object or field. Polarimetry assays include circular dichroism, which may provide structural information and light scattering assays, which may provide information about the size and/or shape of the subject. One nonlimiting example of light scattering assays uses dynamic light scattering (DLS).

As used herein, the terms “colorant” and “chromogen” refer to a compound which produces or provides a detectable change in color, absorbance, turbidity, or other optical property of a medium. Chromagens may be used to signal the occurrence, progress, or results of a chemical reaction, which may be detected and measured by colorimetric or other means (e.g., by luminometer, spectrophotometer, or other light detector).

As used herein, the terms “product formation,” “colored product,” “colored product formation,” and the like are used to refer to the act of, and the products that result from, addition of a colorant to a solution. For example, addition of a colorant to a solution may result in a reaction effective to alter an optical property of the solution. Such a reaction may result in the formation of molecules originally not present in the solution, or may result in the aggregation of molecules or compounds previously in the solution, or may result in the degradation or other alteration of molecules or compounds previously in the solution, effective to alter the color, absorbance, and/or other optical properties of a solution to which a colorant is added.

As used herein, the terms “reflex” and “reflex testing” refer to the initiation, modification or repetition of a protocol, measurement, assay method, or analysis based on information or results obtained following an initial measurement, assay, or analysis. A reflex test may be performed where information is obtained by an initial measurement that can be supplemented by further testing, suggests that a more precise or specific test should be performed, or that an additional test should be performed for an analyte or condition related to or suggested by the initial measurement. Typically, a reflex test is performed based on the results of an initial test; the initial test is typically less sensitive, cheaper or faster than the reflex test. For example, reflex testing may occur when, after detecting a possible abnormality with an initial PAP smear, a more specific or precise test, such as one using nucleic acid analysis, may be performed to more accurately assess the subject's condition. Another example of reflex testing might include measurement of the folate level in the blood of a subject based on finding a low hematocrit level in an initial blood test.

As used herein, the terms “sample” and “biological sample” include the entire sample and include a portion, or portions, of the entire sample, unless the context clearly dictates otherwise. A “sample” may include, but is not limited to, a sample selected from the group consisting of blood, serum, plasma, a nasal swab. a nasopharyngeal wash, saliva, urine, tears, a gastric fluid, spinal fluid, stool, mucus, sweat, earwax, oil, a glandular secretion, cerebral spinal fluid, tissue, semen, vaginal fluid, a throat swab, breath, hair, finger nails, skin, biopsy tissue or fluid, placental fluid, amniotic fluid, cord blood, lymphatic fluids, cavity fluids (e.g, a fluid collected or drained from a body cavity of a subject), sputum, mucus, pus, microbiota, meconium, breast milk and other secretions and excretions.

As used herein, “processing” a sample refers to actions taken to receive, modify, test, represent, and characterize a sample, and may include diluting a sample, subjecting a sample to treatment (e.g., centrifugation, filtration, or other treatment), fractionating or separating sample constituents, contacting a sample with a reagent, staining or dying a sample, observing a sample, testing a sample, or other action, e.g., for determination of characteristics or properties of the sample, Processing a sample may include obtaining an image or representation of a sample or sample constituents,

As used herein, the term “sample collection site” refers to a location at which a sample may be obtained from a subject. A sample collection site may be, for example, a retailer location (e.g., a chain store, pharmacy, supermarket, or department store), a provider office, a physician's office, a hospital, the subject's home, a military site, an employer site, or other site or combination of sites. As used herein, the term “sample collection site” may also refer to a proprietor or representative of a business, service, or institution located at, or affiliated with, the site. Thus, for example, the phrases “an electronic bill from the designated sample collection site” and “an electronic payment from the designated sample collection site” refer to a bill or payment from the proprietor, or the representative of the proprietor, located at, or affiliated with, the sample collection site.

As used herein, the terms “retailer”, “retailer site, “retail site”, and the like, refer to a location at which a retail operations (sales and other commercial transactions) occur. As used herein, these terms may also refer to a proprietor or representative of a business, service, or institution located at, or affiliated with, the retail site.

As used herein, the phrase “no processing of the sample by the subject or by an operator” and linguistic equivalents means that a sample, such as a blood sample, urine sample, stool sample, or other sample, may be placed directly in a container for further processing, and that no action other than those required to effect the placement of the sample in the container is required.

As used herein, “numerical values”, such as, e.g., numerical values representative of a physical process or chemical reaction performed by the device, refer to output of a sensor, detector, or other component or device for measuring a physical parameter such as light intensity, absorbance of light, temperature, pH, or other parameter useful for the measurement of a physical process or chemical reaction. Such numerical values may be analog values (i.e., continuous variables) or digital values (i.e., discrete variables), and may be summed, averaged, normalized, binned, or otherwise manipulated as needed or convenient for the measurement.

As used herein, “electronic data representative of an image” refers to electronic output of a camera, microscope, charge-coupled device, or other sensor capable of providing data that can be used to form an image or a representation of an image. Where configured to form or provide an image (e.g., in arrays), sensors and components including photodiodes, photomultiplier tubes, photoelectric cells, and other light-sensitive electronic components may be used to provide, in whole or in part, electronic data representative of an image.

As used herein, the term “data” includes all information, in any form, obtained from or related to a test, measurement, or observation of a sample (including a portion of a sample) or a reaction in which a sample participates. Data includes raw data, pre-processed data, and processed data.

As used herein, “raw data” includes signals and direct read-outs from sensors, cameras, and other components and instruments which detect or measure properties or characteristics of a sample. For example, raw data includes voltage or current output from a sensor, detector, counter, camera, or other component or device; raw data includes digital or analog numerical output from a sensor, detector, counter, camera, or other component or device; and raw data may include digitized or filtered output from a sensor, detector, counter, camera, or other component or device. For example, raw data includes the output of a luminometer, which may include output in “relative light units” which are related to the number of photons detected by the luminometer. Raw data may include a JPEG, bitmap, or other image file produced by a camera. Raw data may include cell counts; light intensity (at a particular wavelength, or at or within a range of wavelengths); a rate of change of the output of a detector; a difference between similar measurements made at two times; a number of events detected; the number of events detected within a pre-set range or that meet a pre-set criterion; the minimum value measured within a time period, or within a field of view; the maximum value measured within a time period, or within a field of view; and other data. Where sufficient, raw data may be used without further processing or analysis; typically, raw data is further processed or used for further analysis related to the sample, the subject, or for other purposes.

As used herein, “pre-processed” data includes data derived from raw data that has been baseline corrected, filtered, summed, averaged, normalized, scaled, or otherwise manipulated. Pre-processed data may include binned data, or transformed data (e.g., time domain data transformed by Fourier Transform to frequency domain), or may be combined with other data. The pre-processing may put the data into a desired form, and may involve modifying the format of data; however, data pre-processing does not perform actual data analysis or comparison with any threshold values, and does not alter the content of the data.

As used herein, “processed data” includes data and analyses resulting from combination, manipulation or analysis of raw data, pre-processed data, or other processed data. Processing may include comparison (e.g., with a baseline, threshold, standard curve, historical data, or data from other sensors), combination, mathematical manipulation or correction, curve-fitting, use of data as the basis of mathematical or other analytical reasoning (including deductive, inductive, Bayesian, or other reasoning), and other forms of processing known to those of skill in the art.

As used herein, the term “immunoassay” refers to tests which utilize antibodies (including antibody fragments) and their binding to target molecules to label, identify, quantify, or otherwise provide information regarding the presence, amounts, and properties of target molecules and samples containing them. One useful immunoassay that can be run on a device disclosed herein is an ELISA (Enzyme-Linked ImmunoSorbent Assay) Immunoassays also include, for example, competitive binding assays, sandwich assays, Western blots, and other assays utilizing antibodies and antibody fragments.

As used herein, the term “nucleic acid” refers to molecules formed of chains of nuclecotides, such as deoxyribonucleic acid molecules (DNA), ribonucleic acid molecules (RNA), and including locked nucleic acids, “peptide nucleic acids” (PNA) and other nucleic acid analogs similar to, or which mimic, DNA or RNA.

As used herein, the term “nucleic acid assay” refers to any and all assays which utilize nucleic acids or which detect nucleic acids in a sample. Nucleic acids hybridize to complementary nucleic acids, a property which is useful for identifying target nucleic acids, and for identifying samples, whether fluid, tissue, or other samples, containing target nucleic acids. Nucleic acid assays use, and include, techniques for amplifying target nucleic acids (e.g., by producing copies of target nucleic acids, or copies of nucleic acids that are complementary to target nucleic acids). Nucleic acid assays include, for example, assays using polymerase chain reaction (PCR), Southern blots, Northern blots, and other assays which may identify and allow detection of nucleic acids in a sample.

As used herein, the term “receptor-based assay” refers to an assay which utilizes, or detects, the binding of a receptor to its ligand, or the dissociation of a ligand from its receptor. Such assays may use the binding directly to detect or quantify the presence or amount of a receptor or ligand, may use competitive binding techniques to detect or quantify the presence or amount of a target molecule in a sample, or may detect or quantify the presence or amount of a target by use of other methods based on binding between a receptor and ligand or ligands.

As used herein, the term “enzymatic assay” refers to an assay which utilizes, or detects, the presence or action of an enzyme. For example, an assay which provides a substrate for a target enzyme, and detects the presence of that enzyme, or quantifies the activity of that enzyme in a sample following addition of the substrate is an enzymatic assay. An assay which utilizes the enzymatic production of a detectable substance is another example of an enzymatic assay; for example, colorimetric assays (e.g., in which a detectable product is produced by an enzyme, which may be an endogenous enzyme or which may be supplied with the assay reagents) such as assays in which horseradish peroxidase or alkaline phosphatase is used to produce a colored product as an indicator of the progress of the reaction or presence of a target, are enzymatic assays.

As used herein, “Clinical Laboratory Improvement Amendments” and “CLIA” refer to sections of 42 U.S.C. Part F, e.g., subpart 2, sections 263a through 263a7, Federal Regulations 42 CFR Chapter W (sections 493.1 to 493.2001), and related laws, regulations, and as amended. Regulations pursuant to CLIA are administered by the Centers for Medicare and Medicaid Services (CMS) of the United States Department of Health and Human Services.

FIG. 1A shows a system comprising a laboratory 110, a designated sample collection site 120, and a health care professional 100. A device 130 may be provided at the designated sample collection site. A sample collection site may be a first location, and a laboratory may be provided at a second location. The first location and the second location may be different locations. The first and second locations may be located so that they are not proximate to one another. A health care professional may be provided at a third location, although he/she may be affiliated with, employed by, or contracted by the laboratory. The third location may be a different location from the first and second locations. The third location may be located so that it is not proximate to the first or second locations. A laboratory, health care professional, and sample collection site may all be at different locations from one another. In one example, a laboratory, health care professional, and/or sample collection site may be at separate facilities. Alternatively, one or more of them may be at the same location.

A laboratory can be an entity or facility or system or device capable of performing a clinical test or analyzing collected data. A laboratory can provide controlled conditions in which scientific research, experiments, and measurement can be performed. The laboratory can be a medical laboratory or clinical laboratory where tests can be done on clinical specimens, or analysis can occur on data collected from clinical specimens, in order to get information about the health of a patient as pertaining to the screening, diagnosis, prognosis, treatment, and/or prevention of disease. A clinical specimen may be a sample collected from a subject. Preferably, a clinical specimen may be collected from the subject at a sample collection site that is at a separate facility from the laboratory, as described in further detail elsewhere herein. The clinical specimen may be collected from the subject using a device, which is placed at a designated sample collection site or in or on the subject.

In some embodiments, a laboratory may be a certified laboratory. The certified laboratory may be an authorized analytical facility. In some embodiments, authorized analytical facilities may include contracted analytical facilities. For example, a certified laboratory or other laboratory may send images to experts at another laboratory (which may be a certified laboratory) for analysis.

Any description herein of a laboratory may apply to an authorized analytical facility and vice versa. In some instances, the laboratory may be certified by a governmental agency or professional association. A laboratory may receive certification or oversight by a regulatory body. In one example, the laboratory may be certified by an entity, such as Centers for Medicare & Medicaid Services (CMS), College of American Pathologists, ISO standards 15189 or 17025 or equivalents thereof. For instance, an authorized analytical facility may be a Clinical Laboratory Improvement Amendments (CLIA) certified laboratory in the United States or its equivalent in a foreign jurisdiction.

An authorized analytical facility is typically subject to oversight or regulation. For example, a laboratory may have oversight by a board-certified entity (which may include one or more board-certified personnel). In some embodiments, oversight can include validating one or more clinical test. Oversight may also include assessing the performance of, correcting, calibrating, running controls, replicates, adjusting, or analyzing one or more clinical test. Oversight can include evaluation of one or more sets of data to provide a quality control for a clinical test. The authorized analytical facility can have one or more qualified person providing the oversight. For example, one or more pathologist or other health care professional may review data and/or analysis that is processed by the facility. At an authorized analytical facility, a trained pathologist or other certified health care professional may provide oversight. In some instances, the certified health care professional providing oversight may be one or more of the following: a doctor certified in pathology, a doctor with laboratory training or experience in the specialty areas of service for which the health care professional is responsible, or an individual with experience or laboratory training in the specialty.

The oversight may further include the certified health care professional who may establish the procedures and rules in the laboratory, deal with problems that arise, and/or train/evaluate the lab personnel. Oversight may also include selecting test methodology, verifying test procedures and establishment of laboratory's test performance characteristics, enrollment in participation in an HHS approved proficiency testing program, establishing a quality control program appropriate for the testing performed, establishing the parameters for acceptable levels of analytic performance, ensuring that those levels are maintained throughout the entire testing process, resolving technical problems and ensuring that remedial actions are taken when test systems deviate from the established performance specifications, ensuring patient test results are not reported until all corrective actions have been taken, identifying training needs and assuring that each individual performing tests receives regular in-service training and education, evaluating the competency of all testing personnel and assuring that the staff maintain their competency to perform test procedures (e.g., also procedures for evaluation of the staff: direct observation of routine test performance, monitoring the recording/reporting of results, review of intermediate test results, records, etc, observation of performance of instrument maintenance, assessment of test performance, assessment of problem solving skills), and/or evaluating and documenting the performance of individuals responsible for moderate complexity testing (e.g., semiannually during the first year; thereafter, at least annually unless test methodology or instrumentation changes). Oversight may include reviewing and/or verifying functionality of laboratory procedures or devices, and/or validity of data collected and/or generated. The oversight may assure the quality of the rest and/or put the data into a condition upon which a health care professional can rely upon it to provide a screening, diagnosis, treatment, including but not limited to prophylactic treatment. Oversight may include reviewing a test empirically. Oversight may include one or more, two or more, or any of the number of items described elsewhere herein.

In some instances, the oversight may be provided by an oversight software program rather than the certified health care professional. In some instances, one, two or more of the types of oversight provided may be implemented by an oversight software program. A combination of an oversight software program and health care professional may be employed to provide oversight. In some instances, one, two or more of the types of oversight may be implemented by a health care professional over a software program. For example, the health care professional may determine the procedures and rules associated with the software program. In some instances, the software program may be self-learning. The software program may access an increasing pool of data and/or evolving rules or procedures.

In some embodiments, the oversight software program may be provided on a device. The oversight software program may be provided at a sample collection site, on or off the device. The software program may be provided a laboratory, such as an authorized analytical facility. In some instances, the device may receive updates to the oversight software program. The updates may or may not be provided by the laboratory. The oversight software may be stored in a memory, and may include computer readable media comprising code, instructions, or logics that may be capable of executing a step.

In some instances, the oversight software may include one or more algorithm that may review a qualitative and/or quantitative evaluation of the sample that may be performed. The oversight software program may look for outliers, may determine whether the qualitative and/or quantitative evaluation was properly performed, may perform one or more comparison with records or data points, may perform statistical analysis of the evaluation, or any other oversight action as described elsewhere herein. The oversight software may be able to perform one or more calibrations and/or diagnostics.

A health care professional of an authorized analytical facility may receive and/or view data. A health care professional of an authorized analytical facility may be affiliated with or associated with the authorized analytical facility. In some instances, the health care professional may be employed by or under contract with the authorized analytical facility. The health care professional may be located at the authorized analytical facility, may be located remotely from the authorized analytical facility, or in another analytical facility (e.g., hospital, center of excellence, specialized leading path/group). In some instances, the health care professional is not required to be on-site at all times while testing is performed, or when data is received at an authorized analytical facility, but may be available on an as needed basis to provide consultation. The health care professional may be accessible to provide on-site, telephone and/or electronic consultation.

The health care professional providing oversight may be a different individual from or the same individual as the health care professional that may receive a report from the authorized analytical facility for diagnosing, treating, monitoring, or preventing a disease for the subject. For example, a pathologist of an authorized analytical facility may be a different individual from a prescribing physician of the subject. A health care professional of authorized analytical facility may be a reviewing health care professional or an overseeing health care professional. The health care professional who may receive the report may be the health care professional who has ordered the test that the subject has undertaken. A different health care professional may provide analysis, and a different health care professional may provide oversight. Alternatively, the same health care professional may provide both analysis and oversight.

A designated sample collection site may be a point of service (POS) location. Any disclosure herein of a sample collection site may also apply to a point of service location and vice versa. A point of service location where a sample may be collected from a subject or provided by a subject may be a location remote to the laboratory. The sample collection site may have a separate facility from a laboratory. The sample may or may not be collected fresh from the subject at the sample collection site. Alternatively, the sample may be collected from the subject elsewhere and brought to the sample collection site. A sample collection site at a point of service location may be a blood collection center, or any other bodily fluid collection center. The sample collection site may be a biological sample collection center. In some embodiments, a sample collection site may be a retailer. Examples of retailers are provided in further detail elsewhere herein. Other examples of sample collection sites may include hospitals, clinics, health care professionals' offices, schools, day-care centers, health centers, assisted living residences, government offices, traveling medical care units, mobile units, emergency vehicles (e.g., air, boat, ambulance), or the home. For example, a sample collection site may be a subject's home. A sample collection site may be at a sample acquisition site and/or health assessment and/or treatment locations (which may include any of the sample collection sites described elsewhere herein including but not limited to emergency rooms, doctors' offices, urgent care, tents for screening (which may be in remote locations), a health care professional walking into someone's house to provide home care). A sample collection site may be any location where a sample from the subject is received by the device. Any location may be designated as a sample collection site. The designation may be made by any party, including but not limited to the laboratory, entity associated with the laboratory, governmental agency, or regulatory body.

Hydrogen peroxide, in the presence of horseradish peroxidase and colorants such as an amino-antipyrene (e.g., 4-aminoantipyrene) and an aniline-containing compound (e.g., N-Ethyl-N-(2-hydroxy-3-sulfopropyl)-3,5-dimethoxyaniline) may react to form a colored product (e.g., a Trinder (e.g., quinoneimine) dye as indicated in the figure).

For example, HRP may react with an aniline-containing compound such as N-Ethyl-N-(2-hydroxy-3-sulfopropyl)-3,5-dimethoxyaniline (ALPS), or with an aminoantipyrene compound such as 4-aminoantipyrene or with phenolic compounds. Thus, for example, a peroxidase (e.g., HRP, myeloperoxidase, or other peroxidase), an aniline-containing compound, and an aminoantipyrene may all be termed “colorants” or “chromagens.” In further examples, HRP may react with a benzidine-containing compound (e.g., with diaminobenzidine (DAB); tetramethylbenzidine (TMB); 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (DABS); 3-dimethylaminobenzoic acid (DMAB); hydroquinone; o-tolidine; o-phenylenediamine; o-chlorophenol; p-hydroxy-benzenesulfonate; p-anisidine; a Trinder reagent (such as 4-aminoantipyrene, methylbenzothiazolinonehydrazone (MBTH), or other compound for producing a Trinder dye); and derivatives and related compounds) to form a colored product. HRP or other peroxidase may also react with other compounds to form a chemiluminescent product; for example, HRP or other peroxidase may react with luminol to form a chemiluminescent product (other molecules may be present, and may enhance such reactions; for example, HRP-mediated production of luminescent products from luminol is enhanced in the presence of 4-iodophenol).

Further chromagens include, for example, alkaline phosphatase; resazurin (7-Hydroxy-3H-phenoxazin-3-one 10-oxide); 10-acetyl-3,7-dihydroxyphenoxazine (Amplex Red) and similar compounds (e.g., Amplex UltraRed (A36006 from Life Technologies, Carlsbad, Calif. 92008); resorufin compounds (e.g., 7-ethoxyresorufin); dyes such as e.g., fluorescein, calcein, rhodamine, and ethidium dyes; N-methyl-4-hydrazino-7-nitrobenzofurazan; acridinium (acridine-9-carboxylic acid) esters and compounds which react with these compounds to alter an optical property of a solution; phenols and phenol derivatives (e.g., p-iodophenol and p-phenylphenol); luminescent amines, including amine adducts (e.g., as may be derived from copper cyanide), and other molecules. It will be understood that other enzymes and reactants may be used to form colored products, or to detect an analyte in a biological sample, such as a blood sample.

In some examples, the data may be one or more image, and/or audio data representative of the sample. An image may be a digital image or an analog image. The audio data may be digital and/or analog. The data may include a video representative of the sample. An image may include a video image. The data may include electronic data representative of a digital image and/or audio data of the sample. In one example, the data may include video imaging that may capture changes over time. For example, a video may be provided to provide evaluation on dynamic actions, such as lysing, agglutination, mixing, movement of cells or other molecules in a sample or matrix, or assays.

The data may be collected at one time, or at a plurality of times. The data may be collected at discrete points in time, or may be continuously collected over time. Data collected over time may be aggregated and/or analyzed. In some instances, data may be aggregated and may be useful for longitudinal analysis over time to facilitate screening, diagnosis, treatment, and/or disease prevention.

Data may be collected from a device over time. The aggregated data from a single device for a given sample may be useful to facilitate the qualitative and/or quantitative evaluation of the sample. For example, it may be useful to determine how a sample reacts and/or changes over time in order to provide a screening, diagnosis, treatment, and/or disease prevention.

In some embodiments, data may be displayed in a lab report, medical record, or any other type of display. The display may show patient health, provider's level of care, disease regression, progression, and/or onset through longitudinal analysis of high integrity data that is may be obtainable more frequently or obtained frequently through the described infrastructure over time.

Data may be collected from multiple devices. The aggregated data from multiple devices may be useful to facilitate the qualitative and/or quantitative evaluation of the sample. The aggregated data may include data relating to samples collected from a single subject, received at the multiple devices. Alternatively, the aggregated data may include data relating to samples collected from other subjects, received at the multiple devices. The aggregated data may be collected and/or stored in a database. The database may be accessed to provide data to perform a longitudinal analysis that takes past collected data into account. Trends, and changes over time may be monitored. The multiple devices may be standardized and/or may provide data that is of sufficient quality, precision, and/or accuracy in order to aggregate the data and perform a longitudinal analysis therefrom. Very little or no variation may be provided between devices. The devices may also create standardized environments in which the sample preparation may occur. The standardized environments may also be provided during a chemical reaction. The devices may also provide standardized pre-analytic steps. The multiple devices may be distributed globally. This may provide a global evaluation infrastructure, which may better permit the monitoring of disease progression and/or regression. By standardizing a device, data may be longitudinally analyzed looking at velocity of markers in one or more subject over time. The data may be analyzed and/or displayed in a form of lab report or electronic medical record or decision support system for consumers, providers, and/or payers (e.g., health plans, employers, governmental payers, etc.). Such display may include displays of data over time, which may include trending analysis or other analysis relating to changes in values, rates of changes, or rates of rates of change.

The data may be of a quality suitable for a longitudinal analysis over time. The suitable quality of data may be useful for lab reports and/or electronic medical records that may incorporate data collected over time. This may include data collected over long periods of time (e.g., multiple visits, or based off multiple samples), or shorter periods of time (within a single visit, or based on single received sample). The data may have a sufficient quality, precision, and/or accuracy for longitudinal analysis. For example, the sample may be collected from a subject a plurality of times. The sample may be collected from the subject at different times. The samples may be collected at predetermined intervals or according to a predetermined schedule. Alternatively, samples may be collected from the subject when one or more condition or event triggers the collection. Multiple collections of samples may permit the sample to be analyzed over a period of time, thereby permitting longitudinal analysis. In some embodiments, in order to permit longitudinal analysis, the data may have a high degree of precision and/or accuracy. In one example, the data may have a coefficient of variation of 20% or less, 15% or less, 10% or less, 9% or less, 8% or less, 7% or less, 6% or less, 5% or less, 4% or less, 3% or less, 2% or less, 1% or less, 0.5% or less, or 0.1% or less over time. In some instances, the multiple devices may provide data having a coefficient of variation of 20% or less, 15% or less, 10% or less, 9% or less, 8% or less, 7% or less, 6% or less, 5% or less, 4% or less, 3% or less, 2% or less, 1% or less, 0.5% or less, or 0.1% or less over time.

The data over time may be analyzed longitudinally. This may include the change in data over time, the rate of change of data over time, the rate of change of the rate of change of data over time, or any derivative thereof. For example, velocity and/or acceleration of data change may be collected and/or analyzed. The increase and/or decrease in the data values and/or the various rates of change may be beneficial in determining a screening, diagnosis, treatment, and/or disease prevention.

The device is capable of processing a sample collected from a subject to yield data for subsequent analysis. The device may be configured to facilitate collection of the sample from the subject. The device may be configured to receive the sample from the subject. The device may be configured to prepare the sample for a clinical test to detect and/or quantitate an analyte of interest. The device may comprise one or more reagents useful for the clinical test. The preparation or the clinical test may include a chemical reaction with the reagents. The device may include one or more detector that may be capable of detecting signals generated from processing the sample. The device may transmit data relating to the sample. The data relating to the sample may include the raw data from the detected signals, such signals relating to unreacted sample, a sample that has undergone a reaction, and/or device configurations. In some instances, the device may pre-process some of the raw data to get it into a desired format, and transmit the pre-processed data. In some instances, the device may perform one or more analysis step, and transmit analyzed data. Alternatively, the device does not perform any pre-processing and/or analysis. The pre-processing and/or analysis may occur at the laboratory. In some instances, pre-processing and/or analysis may occur at both the device and the laboratory. The laboratory may also include a hospital who may be leveraging its pathologists so data can be transmitted to centers of excellence for the analysis of different types of specific conditions.

In embodiments, a device may monitor its environment, including its internal and external environment. In embodiments, a device may provide device environmental information to a laboratory. Device environmental information includes, e.g., internal temperature, external temperature, internal humidity, external humidity, time, status of components, error codes, images from an internal camera, images from an external camera, air pressure (barometric pressure), and other information. In embodiments, an internal camera may be fixed at an internal location. In embodiments, an internal camera may be fixed at an internal location and may be configured to rotate, scan, or otherwise provide views of multiple areas or regions within the device. In embodiments, an internal camera may be movable within the device; for example, an internal camera may be mounted on a movable element, such as a pipette, within the device. In embodiments, an internal camera may be movable within the device and may be configured to rotate, scan, or otherwise provide multiple views of areas within the device from multiple locations within the device. In embodiments, an external camera may be fixed at an external location. In embodiments, an external camera may be fixed at an external location and may be configured to rotate, scan, or otherwise provide multiple views of areas outside the device. In embodiments, an external camera may be movable on or around the outside of the device. In embodiments, an external camera may be movable and may be configured to rotate, scan, or otherwise provide multiple views of areas outside the device from multiple locations on or around the outside of the device.

Thus, in embodiments, monitoring, and reporting the results of such monitoring, of the device environment may be part of the oversight of the operation of the device and of the integrity of results and analysis. Such monitoring provides information, oversight, and control of quality regarding the device and its output (of the condition, operation, results generated, and data transmitted). Such monitoring may include: measurement and control of air temperature; measurement and control of liquid (volume, temperature, mixing, etc.); monitoring of sample collection; imaging of a cartridge to determine the position of a cartridge in the device; imaging of a cartridge to correct its position, if necessary, per such imaging of the cartridge in the device; imaging of tips to confirm proper engagement with pipette nozzles; imaging of liquid volumes in tips; imaging of bubbles in liquids, if any; imaging of samples to assess sample volume, sample quality and presence or absence of conditions which may interfere with proper processing or analysis (such as hemolysis, lipemic, icteric conditions of a sample); feedback control and error detection of status and condition of motors on a pipette for control and oversight concerning accurate aspiration and dispensing of liquids; feedback control and error detection of a centrifuge for precise centrifugal force control, determination of position, and other information regarding status and condition of a centrifuge; feedback control and error detection for gantry, robots and shuttle positions, including or oversight and control of the positioning of pipettes, cartridges, and tips/cuvettes for processing and analysis of a sample; control of reactions (between a sample and a reagent) to confirm proper device operation (e.g., using sensors, pipette, gantry, thermal sensors and control, etc.); monitoring and control of the proper state of reagents; the running of control reactions at the same time as the sample analysis, or beforehand or subsequently; performance of replicate analysis of the sample to enhance precision; performing blank reads to control for possible changes in background signals in samples and for possible small fluctuations in sensor performance and in output of light sources.

In embodiments, monitoring, and reporting the results of such monitoring, may include calibration. Calibration of the device, reagents, disposables, and of their manufacture and assembly may be part of the oversight of the operation of the device and of the integrity of results and analysis. During manufacturing, each device is calibrated to a set of controlled standards. During manufacturing, reagents and disposables (e.g., tips, cuvettes, and other elements) is calibrated to a set of controlled standards, and identification information related to each cartridge containing these reagents and disposables includes information about these calibrations. Such calibration may include: each pipette nozzle of each pipette is calibrated—for example, for each pipette nozzle, information regarding how a given displacement of the motor translates to a given amount of liquid volume is measured and provided in the information recorded for each motor for use in protocols used with the device in which that motor is a component; each sensor and illumination source in a device is calibrated against a set of controlled standards, and provided in the information for each device, so that the resulting signals from all sensors across all devices results in the same measurement; each motor control algorithm is calibrated during manufacturing such that speeds and position of the motors can be controlled similarly across each device; each camera and each illumination source is characterized, including a flat field correction; during manufacturing, each of lot reagents is calibrated such that any change in potency of the reagents still results in the same analytic result. Thus, since each sample is analyzed by processing on the device (for which such component and device specific calibration information is known) the raw data resulting from sample processing can be calibrated and corrected according to the information and calibrations for each reagent, and each device and its components. Such oversight and calibration insures the integrity of the results obtained, and thus also provides for the integrity of analysis of such results. The raw data from a device is analyzed by utilizing the device-specific calibration and the reagent lot-specific calibration to arrive at the result. Each result arrived at in this way is thus accurate, precise, and reliable, and may be compared with analogous results obtained from other samples in the same instrument, and with other instruments and samples, reducing variance and errors and allowing for better analysis and better confidence in diagnoses and inferences drawn from the analysis of samples.

Quality control runs may be performed on a device and reagents on a periodic basis, e.g., as overseen by CLIA, to ensure that the reagents and devices are still performing within specifications. If discrepancies are found, reagents and/or devices may be determined to need recalibration. Devices can be recalibrated in the field by running defined protocols, which may or may not require inserting a calibration cartridge into the device. Reagents may be recalibrated by generating a standard curve using the same lot of reagents and deriving a calibration function. Such reagent recalibration can performed on any one of the devices and can be applied to all devices.

Transmission of device environmental information to a laboratory is useful for the oversight and control of the device, including being useful for the oversight and control of the operation of the device. Transmission of device environmental information to a laboratory is useful for maintaining the integrity of the operation and control of the device, quality control of the operation and control of the device, and for reducing variation or error in the data collection and sample processing performed by the device. Device environmental information may be used, for example, by a laboratory to modify, correct, or update a protocol or other instruction or command to a device. Device environmental information may be used, for example, by a laboratory to modify, correct, or update an analysis of data received from a device. For example, transmission of temperature information to a laboratory is useful for the oversight and control of the device, and is useful in the analysis by the laboratory of data provided by the device to the laboratory.

In embodiments, a device may be configured to control the temperature within the device, or within a portion of the device. Such control improves the reproducibility of measurements made within the device, may unify or provide regularity of conditions for all samples, and reduce the variability of measurements and data, e.g., as measured by the coefficient of variance of multiple measurements or replicate measurements. Temperature information may be useful for quality control. In embodiments, a device may monitor temperature and control its internal temperature. Temperature control may be useful for quality control. A device that monitors and controls its temperature may transmit temperature information to a laboratory; a laboratory may use such temperature information in the control of the operation of the instrument, in the oversight of the instrument, and in the analysis of data transmitted from the instrument.

In embodiments, a device may be configured to acquire images from within the device, or within a portion of the device. Such images may provide information about the position, condition, availability, or other information regarding components, reagents, supplies, or samples within the device, and may provide information used in control of the operation of the device. Such images may be useful for quality control. A device that acquires images from within the device may transmit image information to a laboratory; a laboratory may use such image information in the control of the operation of the instrument, in the oversight of the instrument, and in the analysis of data transmitted from the instrument.

In one scenario, a device may perform a sample preparation step without performing any analysis or receiving any oversight. The data from the sample preparation step may be sent to the laboratory, which may perform the analysis, and which may be an authorized analytical facility that includes oversight. In another scenario, the device may perform one or more sample preparation step and may perform analysis on board. Data from the analysis may be sent to an authorized analytical facility, which may provide oversight. Alternatively, oversight may occur on board the device.

In some embodiments, oversight may include a review of the data in raw form, pre-processed form, or after analysis. Oversight may occur of a qualitative and/or quantitative evaluation of the sample. Examples of a qualitative evaluation of the sample may include but are not limited to review of an image, video, or audio file. Examples of a quantitative evaluation of the sample may include a numerical value indicating a presence or concentration level of a signal, series of signals, or an analyte. Oversight may include one or more, or two or more of the examples provided elsewhere herein. Oversight may be provided by a health care professional of an authorized analytical facility. In some other instances, oversight may be provided by a software program or automated review system. The software program and/or automated review system may or may not be under the review or care of a qualified person, such as a health care professional (such as a laboratory director).

The device may duplicate manual analytical procedures. In some instances, the device may perform automatically various steps, such as pipetting, preparing filtrates, heating, and/or measuring color intensity. The device may be used in conjunction with materials to measure one or more analytes. The device may measure the presence or concentration of one or more analytes. The device may include reagent-containing components that may serve as reaction units. Examples of device components and steps that may be taken by the device can be described in greater detail elsewhere herein.

The laboratory may communicate with a health care professional. The laboratory may generate a report based on analyzed data. In some instances, the laboratory may analyze raw data or pre-processed data provided from the device. Alternatively, the laboratory may receive analyzed data from the device. The laboratory may or may not perform further analysis and/or oversight from analyzed data received from the device.

The laboratory and/or device may generate a report that may present the analyzed data in a meaningful or desired manner. The report may have a format that may enable a viewer of the report to rely on the report to make a medical determination. The laboratory and/or device may transmit the report to a health care professional (or laboratory director). In some embodiments, a pathologist, other health care professional, or other qualified person may review the report prior to transmitting the report to the health care professional. A reviewing health care professional may review the report or qualitative and/or quantitative evaluation useful for generating the report prior to transmission to an ordering health care professional. Review or oversight may occur of the analyzed data and/or report at the laboratory. Alternatively, review or oversight may occur on-board the device. The health care professional who receives the report may or may not rely on the report for screening, diagnosis, treatment and/or disease prevention of the subject.

The laboratory and/or device may also provide a report to the subject. The report provided to the subject may be the same as or different from the report provided to the health care professional. The report provided to the health care professional may have more detail or vice versa. The formats between the reports provided to the subject and the health care professional may or may not vary. Alternatively, the laboratory and/or device does not provide a report to the subject. The subject may receive information based on the report from the health care professional. A device or laboratory can directly provide a lab report automatically to a consumer upon a test being performed and/or analysis being done, or being sent to a physician for review and/or after the physician's review.

Any transmission of data and/or reports may incorporate the use of a cloud computing infrastructure. The sending party may provide the data to or have the data on a cloud computing infrastructure. The receiving party and/or parties (e.g., health care professional or patient) may access the cloud computing infrastructure. The cloud computing infrastructure may be provided on the sending party side and/or the receiving party side. Alternatively, traditional fixed data storage techniques may be employed.

FIG. 1B shows a retailer 170 having a processing device 172 in communication with a laboratory 160. The laboratory or reader device may be in communication with a health care professional 150. As previously described, any discussion herein of retailers or other examples of sample collection sites may apply to any type of sample collection site, and vice versa. A retailer may be provided at a first location and a health care professional may be provided at a second location. The first location and the second location may be different locations. In some embodiments, the first and second locations are not proximate to one another. A laboratory may be provided at a third location. The third location may be a different location from the first and/or second location. For example, the first, second, and third locations need not be proximate to one another. The first, second, and/or third locations may be located in different facilities. Alternatively, the first, second, and/or third could all be the same location (point of service).

A retailer may be an entity that sells a product or service. In some embodiments, the product or service may relate to health or medical care. For example, the retailer may sell medicine or health care supplies and/or insurance. In some embodiments, a retailer may be a pharmacy (e.g., retail pharmacy, clinical pharmacy, hospital pharmacy), drugstore, chain store, supermarket, or grocer. Examples of retailers may include but are not limited to Walgreens, CVS Pharmacy, Duane Reade, Walmart, Target, Rite Aid, Kroger, Costco, Kaiser Permanente, or Sears.

A retailer may be provided at a retailer location. In some embodiments, the retailer may be at a different geographic location than a health care professional and/or laboratory location. Alternatively, the health care professional may be provided at the retailer location.

A retailer 170 may have a sample processing device 172 at the retailer's location. In some embodiments, the retailer may have one or more, two or more, three or more, four or more, five or more, six or more, or ten or more sample processing devices at the retailer's location. The sample processing device may be a point of service device. The sample processing devices may be capable of communication with communication-enabled devices. For example, the sample processing devices at a retailer location may communicate with one another. Alternatively, sample processing devices may communicate with other reader devices at different locations, such as other sample collection sites, or in or on a subject. Sample processing devices may communicate with other types of communication-enabled devices, such as a computer at a laboratory and/or biometric devices. Such communications may be wired or wireless.

The sample processing device 172 may be configured to accept a sample. The sample processing device may be configured to collect the sample directly from a subject. The sample processing device may be configured to perform one or more sample preparation step on the subject. The sample processing device may be configured to run an assay. In some embodiments, the sample processing device may be configured to run one or more assay. The sample processing device may be capable of performing multiplexed assays on a single sample. Where desired, the device is configured to perform at least 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 100, 200, 500, 1000 or more assays. The plurality of assays may be run simultaneously in parallel. One or more control assays and/or calibrators (e.g., including a configuration with a control of a calibrator for the assay/tests) can also be incorporated into the device to be performed in parallel if desired. In some instances, assays may be run in sequence, or any combination of in sequence and in parallel, based on the sample. The reader device may be effecting one, two, or more chemical reactions or other processing tests (e.g., pulverizing). The sample processing device may be configured to detect one or more signal relating to the sample. The sample may be a sample of bodily fluid, a biological sample, or any other example as provided elsewhere herein.

In some embodiments, the sample processing device 172 may comprise a cartridge 174. The cartridge may be removable from the sample processing device. In some embodiments, a sample may be provided to the cartridge of the sample processing device. Alternatively, the sample may be provided to another portion of the sample processing device. The cartridge and/or device may comprise a sample collection unit that may be configured to accept a sample. The sample processing device is described in further detail elsewhere herein. The cartridge and device may be integrated into a single device or may be separable devices. A device may include a pill or patch that may link to a mobile device or other network device for processing.

A subject 176 may be provided at the retailer 170. The subject may provide a sample of bodily fluid to the sample processing device 172 and/or cartridge 174 of the device. A bodily fluid may be drawn from a subject and provided to a device in a variety of ways, including but not limited to, fingerstick, lancing, injection, and/or pipetting. The bodily fluid may be collected using venous, or non-venous methods. The bodily fluid may be provided using a bodily fluid collector. A bodily fluid collector may include a lancet, microneedle, porous membrane (e.g., for a pill), capillary, tube, pipette, syringe, venous draw, or any other collector described elsewhere herein. In one embodiment, a lancet punctures the skin and withdraws a sample using, for example, gravity, capillary action, aspiration, or vacuum force. The lancet may be part of the sample processing device, part of the cartridge of the device, part of a system, or a standalone component. Where needed, the lancet may be activated by a variety of mechanical, electrical, electromechanical, or any other known activation mechanism or any combination of such methods. In one example, a subject's finger (or other portion of the subject's body) may be punctured to yield a bodily fluid. The bodily fluid may be collected using a capillary tube, pipette, or any other mechanism known in the art. The capillary tube or pipette may be separate from the device and/or cartridge, or may be a part of a device and/or cartridge. A transfer device may require no additional processing steps, and may be pre-coated with anti-coagulants or other pre-treatments in a single step. In another embodiment where no active mechanism is required, a subject can simply provide a bodily fluid to the device and/or cartridge, as for example, could occur with a saliva sample, or touching a pierced body part to a surface directly. The collected fluid can be placed within the device. A bodily fluid collector may be attached to the device, removably attachable to the device, or may be provided separately from the device.

A cartridge 174 may be inserted into the sample processing device 172 or otherwise interfaced with the sample processing device. The cartridge may be removed from the sample processing device. In one example, a sample may be provided to a sample collection unit of the cartridge. The sample may be provided directly to the cartridge. The sample may or may not be provided to the sample collection unit via a bodily fluid collector. A bodily fluid collector may be attached to the cartridge, removably attachable to the cartridge, or may be provided separately from the cartridge. The bodily fluid collector may or may not be integral to the sample collection unit. The cartridge may then be inserted into the sample processing device. Alternatively, the sample may be provided directly to the sample processing device, which may or may not utilize the cartridge. The cartridge may comprise one or more reagents, which may be used in the operation of the sample processing device. Alternatively, one or more reagents may already be provided onboard the sample processing device.

The cartridge may or may not be disposable. Cartridges may be specially configured for one or more types of clinical tests. For example, a first cartridge may have a first configuration to enable a first set of tests, and a second cartridge may have a second configuration to enable a second set of tests. Alternatively, universal cartridges that may be configured for the same selection of tests may be provided. In some instances, universal cartridges may be dynamically programmed for certain tests through remote or on-board protocols.

When a cartridge is inserted into the sample processing device, one or more components of the cartridge may be brought into fluid communication with other components of the sample processing device. For example, if a sample is collected at a cartridge, the sample may be transferred to other portions of the sample processing device. Similarly, if one or more reagents are provided on a cartridge, the reagents may be transferred to other portions of the sample processing device, or other components of the sample processing device may be brought to the reagents. One or more components of the cartridge may be transferred in an automated fashion to other portions of the sample processing device, and vice versa. In some embodiments, the reagents or components of a cartridge may remain on-board the cartridge. In some embodiments, no fluidics are included that require tubing or maintenance (e.g., manual or automated maintenance).

The sample processing device may be configured to be placed in or on a subject. The sample processing device may receive a sample from the subject through a housing of the device. For example, if the sample processing device is ingestible or implanted within a subject, it may include a housing or a biocompatible coating. The biocompatible coating may be permeable to the desired sample. The sample may penetrate the coating or housing of the sample processing device, thereby being received by the sample processing device. If the sample processing device is on the subject, the sample may be received through the housing and/or coating of the device. Alternatively, the sample may be received using one or more needle or microneedle that may be provided on the device (which may or may not be provided on the cartridge portion of the device).

The sample processing device may be configured to facilitate sample collection, prepare the sample for a clinical test, and/or may comprise one or more reagents useful for a clinical test. In some embodiments, the sample processing device may be configured to run one or more test from the sample. A chemical reaction or other processing step may be performed, with or without the sample. In some embodiments, assays, such as immunoassays or nucleic acid assays may be run. Examples of steps and/or tests that may be prepared or run by the device may include, but are not limited to immunoassay, nucleic acid assay, receptor-based assay, cytometric assay, colorimetric assay, enzymatic assay, electrophoretic assay, electrochemical assay, spectroscopic assay, chromatographic assay, microscopic assay, topographic assay, calorimetric assay, turbidmetric assay, agglutination assay, radioisotope assay, viscometric assay, coagulation assay, clotting time assay, protein synthesis assay, histological assay, culture assay, osmolarity assay, and/or other types of assays, centrifugation, separation, filtration, dilution, enriching, purification, precipitation, pulverization, incubation, pipetting, transport, cell lysis, or other sample preparation steps, or combinations thereof. Sample processing may include chemical reactions and/or physical processing. Sample processing may include the assessment of histology, morphology, kinematics, dynamics, and/or state of a sample, which may include such assessment for cells. The device may perform one or more, two or more, three or more, or four or more of these steps/tests.

Processing of a biological sample may include preprocessing (e.g., preparation of a sample for a subsequent processing or measurement), processing (e.g., alteration of a sample so that it differs from its original, or previous, state), and post-processing (e.g., fixing a sample, or disposing of all or a portion of a sample following its measurement or use). A biological sample may be divided into portions, such as aliquots of a blood or urine sample, or such as slicing, mincing, or dividing a tissue sample into two or more pieces. Processing of a biological sample, such as blood sample, may include mixing, stirring, sonication, homogenization, or other processing of a sample or of a portion of the sample. Processing of a biological sample, such as blood sample, may include centrifugation of a sample or a portion thereof. Processing of a biological sample, such as blood sample, may include providing time for components of the sample to separate or settle, and may include filtration (e.g., passing the sample or a portion thereof through a filter). Processing of a biological sample, such as blood sample, may include allowing or causing a blood sample to coagulate. Processing of a biological sample, such as blood sample, may include concentration of the sample, or of a portion of the sample (e.g., by sedimentation or centrifugation of a blood sample, or of a solution containing a homogenate of tissue from a tissue sample) to provide a pellet and a supernatant. Processing of a biological sample, such as blood sample, may include dilution of a portion of the sample. Dilution may be of an entire sample, or of a portion of a sample, including dilution of a pellet or of a supernatant from sample. A biological sample may be diluted with water, or with a saline solution, such as a buffered saline solution. A biological sample may be diluted with a solution which may or may not include a fixative (e.g., formaldehyde, paraformaldehyde, or other agent which cross-links proteins). A biological sample may be diluted with a solution effective that an osmotic gradient is produced between the surrounding solution and the interior, or an interior compartment, of such cells, effective that the cell volume is altered. For example, where the resulting solution concentration following dilution is less than the effective concentration of the interior of a cell, or of an interior cell compartment, the volume of such a cell will increase (i.e., the cell will swell). A biological sample may be diluted with a solution which may or may not include an osmoticant (such as, for example, glucose, sucrose, or other sugar; salts such as sodium, potassium, ammonium, or other salt; or other osmotically active compound or ingredient). In embodiments, an osmoticant may be effective to maintain the integrity of cells in the sample, by, for example, stabilizing or reducing possible osmotic gradients between the surrounding solution and the interior, or an interior compartment, of such cells. In embodiments, an osmoticant may be effective to provide or to increase osmotic gradients between the surrounding solution and the interior, or an interior compartment, of such cells, effective that the cells at least partially collapse (where the cellular interior or an interior compartment is less concentrated than the surrounding solution), or effective that the cells swell (where the cellular interior or an interior compartment is more concentrated than the surrounding solution).

A biological sample may be dyed, or markers may be added to the sample, or the sample may be otherwise prepared for detection, visualization, or quantification of the sample, a portion of a sample, a component part of a sample, or a portion of a cell or structure within a sample. For example, a biological sample may be contacted with a solution containing a dye. A dye may stain or otherwise make visible a cell, or a portion of a cell, or a material or molecule associated with a cell in a sample. A dye may bind to or be altered by an element, compound, or other component of a sample; for example a dye may change color, or otherwise alter one of more of its properties, including its optical properties, in response to a change or differential in the pH of a solution in which it is present; a dye may change color, or otherwise alter one of more of its properties, including its optical properties, in response to a change or differential in the concentration of an element or compound (e.g., sodium, calcium, CO₂, glucose, or other ion, element, or compound) present in a solution in which the dye is present. For example, a biological sample may be contacted with a solution containing an antibody or an antibody fragment. For example, a biological sample may be contacted with a solution that includes particles. Particles added to a biological sample may serve as standards (e.g., may serve as size standards, where the size or size distribution of the particles is known, or as concentration standards, where the number, amount, or concentration of the particles is known), or may serve as markers (e.g., where the particles bind or adhere to particular cells or types of cells, to particular cell markers or cellular compartments, or where the particles bind to all cells in a sample).

The sample processing device may be configured to perform one, two or more assays on a small sample of bodily fluid. One or more chemical reaction may take place on a sample having a volume, as described elsewhere herein. For example one or more chemical reaction may take place in a pill having less than femtoliter volumes. In an instance, the sample collection unit is configured to receive a volume of the bodily fluid sample equivalent to a single drop or less of blood or interstitial fluid. The sample collection unit may be able to collect a volume of bodily fluid sample without piercing a subject's skin. In one example, light may be shined to optically measure a sample.

A client computer may receive tangible computer readable media, which may contain instructions, logic, data, or code that may be stored in persistent or temporary memory of the client computer, or may somehow affect or initiate action by a client computer. Similarly, one or more devices may communicate with one or more client computers across a network, and may transmit computer files residing in memory. One or more devices may communicate computer files or links that may provide access to other computer files.

At a client computer 204 a, mobile device 204 b, or any other network device as described elsewhere herein, the display page may be interpreted by software residing in memory of the client computer, mobile device, or network device, causing the computer file to be displayed on a video display in a manner perceivable by a user.

In some embodiments, the data can be sent to the email of the laboratory personnel, health care professional, and/or subject.

In some embodiments, the sample processing device may provide data to a cloud computing infrastructure. The network device (e.g., of a laboratory, health care professional, or other entity) may access the cloud computing infrastructure. In some embodiments, on-demand provision of computational resources (data, software) may occur via a computer network, rather than from a local computer. The network device may contain very little software or data (perhaps a minimal operating system and web browser only), serving as a basic display terminal connected to the Internet. Since the cloud may be the underlying delivery mechanism, cloud-based applications and services may support any type of software application or service. Information provided by the sample processing device and/or accessed by the network devices may be distributed over various computational resources. Alternatively, they may be stored in one or more fixed data storage unit or database.

FIG. 3A illustrates a high level example of a sample processing device 300. A sample processing device may be provided at any location, including a sample collection site. The sample processing device may be in or on a subject, or may be carried by the subject. The sample processing device may be easily mobile or transportable. The sample processing device may travel with the subject. The sample processing device may be a benchtop device or a handheld device. The sample processing device may be located remote to a laboratory. Any number of sample processing devices may be distributed geographically in any manner. For example, one or more sample collection sites may have one or more devices.

The sample processing device 300 may be configured to accept a removable cartridge 350. The removable cartridge and/or device may have any other characteristics or components as described elsewhere herein. The removable cartridge may be configured to accept a sample and/or deliver the sample to the device. The removable cartridge may have one or more reagents provided thereon. For example FIG. 3B provides an illustration of one or more reagents provided on the removable cartridge. Alternatively, one or more reagents 370 may be provided on board the device, such as shown in FIG. 3A. The device may comprise one or more reagent units that may contain and/or confine one or more reagents. The reagents may originally be provided on the device, the reagents may be provided to the reagent units from or on the cartridge, or both on-board the device and within the cartridge.

In other embodiments, the sample processing device need not have a removable cartridge. One or more functions as described for the cartridge may be provided by the device itself.

The sample processing device and/or a cartridge may comprise all reagents, liquid- and solid-phase reagents, required to perform one or more of the chemical reactions and/or other processing steps, including physical processing, as described elsewhere herein. For example, for a luminogenic ELISA assay the reagents within the device may include a sample diluent, a detector conjugate (for example, three enzyme-labeled antibodies), a surface labeled with antibodies binders, a wash solution, and an enzyme substrate.

Enzyme-linked ImmunoSorbent assays (“ELISA”) are assays using antibodies to bind a target analyte in a solution or on a substrate. One useful immunoassay that can be run on a device disclosed herein is ELISA. For example, tips having adherent antibodies or target antigens may be used in ELISAs performed by devices and according to methods disclosed herein.

Performing an ELISA generally involves at least one antibody capable of binding an antigen of interest (i.e., an analyte that is indicative of influenza viral infection). A sample containing or suspected to contain the antigen of interest is immobilized on a support (e.g., a tip or other support having a surface for immobilization) either non-specifically (e.g., via adsorption to the surface) or specifically (e.g., via capture by another antibody specific to the same antigen, in a “sandwich” ELISA). After the antigen is immobilized the detection antibody is added, forming a complex with the antigen. The detection antibody can be conjugated to an enzyme, or can itself be detected by a secondary antibody which is in turn conjugated to an enzyme. Upon addition of a substrate for the conjugated enzyme, a detectable signal is generated which indicates the presence and/or quantity of the antigen in the sample. The choice of substrates will depend on the enzyme conjugated. Suitable substrates include fluorogenic and chromogenic substrates. Those of skill in the art would be understand and be able to determine which parameters of such assays that can be modified to increase the signal detected as well as other variations of ELISAs known in the art.

In some ELISAs, a solid phase capture surface can include an attached first antibody to which a sample (e.g., diluted blood, plasma, or biological specimen) can be added. If present, an analyte in the sample can bind to the first antibody and become immobilized. An enzyme reagent can be added that includes, for example, an antibody coupled or conjugated to an enzyme (e.g., alkaline phosphatase or horseradish peroxidase) that produces a detectable product, or can be otherwise detected. If the antibody portion of the enzyme reagent can bind the analyte, then the enzyme reagent also becomes immobilized at the capture surface. Addition of a substrate for the enzyme can result in a product producing an effect, for example, light that can be measured and plotted as shown. In this manner the amount of analyte present in a sample can be measured.

Thus, for example, an exemplary ELISA which may be performed using a device, system, or method as disclosed herein includes a solid phase capture surface (e.g., a tip) on which a first antibody is immobilized. The first antibody is specific for a test antigen (e.g., antibody specific for a target blood analyte, such as cholesterol, or for e.g., neuraminidase on the coat of a virus of interest, or other antigen). If the test antigen is present in a test sample (e.g., whole blood, plasma, or serum) that is exposed to the antibody immobilized on the surface, then the test antigen can become immobilized (captured) at the capture surface. Addition of a second, labeled antibody that binds to the first antibody (e.g., where the first antibody has a biotin label, and the second antibody has an avidin label and a detectable label; or where the first antibody is a sheep antibody including an Fc portion, the second antibody may be an antibody targeting sheep Fc and labeled with alkaline phosphatase (AP) which can be detected following addition of AP substrate) allows the detection and quantification of the amount of antigen in the sample. The first antibody, which is bound to the substrate, is not washed out by the addition of the second antibody. Such detection and quantification may be accomplished by providing substrate for alkaline phosphatase, leading to the production of colored, fluorescent, luminescent (e.g., chemiluminescent), or otherwise detectable compounds which may be detected and measured.

Alternatively, after the blood sample is placed in contact with the surface having the immobilized first antibody (labeled with an enzyme which catalyzes a reaction that produces a first detectable compound) that targets a first antigen, a second antibody, targeting a second antigen and labeled with a second enzyme which can produce a second detectable compound may be added. The first antibody, which is bound to the substrate, is not washed out by the addition of the second antibody, and may be detected by providing the substrate and proper reaction conditions for the production of a first detectable product by enzyme linked to the first antibody. Binding and subsequent detection of the second, labeled antibody at the capture surface indicates the presence of both the first and the second test antigens in the test sample. Both the first and second detectable compounds produced by the enzymes linked to the antibodies may be detected by any means desired, including by detection of fluorescence, luminescence, chemiluminescence, absorbance, or other means for detecting the products of the enzymatic reactions due to the attached enzymes.

For example, photomultipliers tubes, charge-coupled devices, photodiodes, cameras, spectrophotometers, and other components and devices may be used to measure light emitted or affected during the performance of an ELISA. For example, the amount of light detected (e.g., in relative light units, or other measurements of luminosity) during the performance of an ELISA on a sample may be compared to a standard curve (e.g., a calibration curve prepared for a particular assay, device, cartridge, or reagent) to calculate the concentration of the target analyte in the sample. Analytes that have been detected and their levels measured in blood samples using ELISAs performed on devices and systems as disclosed herein include: vitamin B-12, folic acid, thyroxine, testosterone, estradiol, cotinine, vancomycin, hemoglobin A1c, prostate specific antigen, human chorionic gonadotropin, luteinizing hormone, parathyroid hormone, alpha-fetoprotein, prealbumin, cardiac troponin T, C-reactive protein, hepatitis B surface antigen (HbsAg), immunoglobulin E (IgE), immunoglobulin G (IgG), Dengue virus IgG, rheumatoid factor IgM, West Nile Virus IgM, anti-HIV 1 antibodies, anti-HIV 2 antibodies, anti-nuclear antibodies, influenza A, influenza B, and streptococcus.

ELISAs are also used, for example, in competitive binding experiments, in which the concentration of an analyte in a solution may be measured by adding a known amount of labeled analyte, and measuring the binding of the analyte. Increased concentrations of the sample analyte (which does not include the label) interfere (“compete”) with the binding of the labeled analyte, allowing calculation of the amount of analyte in the sample.

Additional reagents can be provided as needed. In some embodiments, reagents can be incorporated into a device to provide for sample pretreatment. Examples of pretreatment reagents include, without limitation, white cell lysis reagents, reagents for liberating analytes from binding factors in the sample, enzymes, and detergents. The pretreatment reagents can also be added to a diluent contained within the device.

Reagents according to the present invention include without limitation wash buffers, enzyme substrates, dilution buffers, conjugates, enzyme-labeled conjugates, DNA amplifiers, sample diluents, wash solutions, sample pre-treatment reagents including additives such as detergents, polymers, chelating agents, albumin-binding reagents, enzyme inhibitors, enzymes, anticoagulants, red-cell agglutinating agents, antibodies, or other materials necessary to run an assay on a device. An enzyme-labeled conjugate can be either a polyclonal antibody or monoclonal antibody labeled with an enzyme that can yield a detectable signal upon reaction with an appropriate substrate. Non-limiting examples of such enzymes are alkaline phosphatase and horseradish peroxidase. In some embodiments, the reagents comprise immunoassay reagents. Reagents defining assay specificity may be provided, which may optionally include, for example, monoclonal antibodies, polyclonal antibodies, proteins, nucleic acid probes or other polymers such as affinity matrices, carbohydrates or lipids. In general, reagents, especially those that are relatively unstable when mixed with liquid, are confined separately in a defined region (for example, a reagent unit) within the device and/or cartridge.

In some embodiments, a reagent unit may contain a small volume of reagent. For example, a reagent unit may contain approximately about 5 microliters or less to about 1 milliliter of liquid. In some embodiments, the unit may contain about 20-200 microliters of liquid. In a further embodiment, the reagent unit contains 100 microliters of fluid. In an embodiment, a reagent unit contains about 40 microliters of fluid. A reagent unit may include any volume described elsewhere herein, which may include volumes of sample. The volume of liquid in a reagent unit may vary depending on the type of assay being run or the sample of bodily fluid provided. In an embodiment, the volumes of the reagents do not have to be predetermined, but must be more than a known minimum. In some embodiments, the reagents are initially stored dry and dissolved upon initiation of the assay being run on the device.

The sample processing device may comprise a display 310. The display may be a video display or other type of user interface. The display may function as a user interface. The display may permit a user to operate the sample processing device. The display may be configured to accept an input from the user relating to a subject identity, other information about the subject, information about the sample, information about one or more clinical test, information about sample preparation steps, information about a laboratory, and/or information about a medical care provider.

The display may output information to an operator of the device. The display may prompt the operator to perform one or more steps in the operation of the device. The display may display information about the sample collected, the subject, and/or data relating to one or more preparation step performed or chemical reaction run. The display may output information about one or more automated process that may be implemented by the device. The display may provide one or more alert for an error detected, or when one or more parameters are met (e.g., certain detected signals exceed a predetermined threshold). A display may display results on the device.

The sample processing device 300 may comprise one or more components useful for collecting the sample, preparing the sample for a clinical test, and/or running a chemical reaction, or other test or analysis. The sample processing device may also comprise one or more components useful for detecting one or more signal relating to the sample or components of the device. For example, the sample processing device may include, but is not limited to, a sample collection unit, centrifuge, magnetic separator, filter, pipette or other fluid handling system, vessels, containers, assay units, reagent units, heater, thermal block, cytometer, spectrophotometer, imaging systems, microscopy station, light source, optical detector, photometer, temperature sensor, motion sensor, or sensor for electrical properties. Fluid may be transferred from one component to another via a fluid handling system, such as a pipette, channels, or pumps.

In some embodiments, the fluid handling system may be a pipettor. The pipettor may be a multi-head pipettor. In some instances, each of the pipette heads may be of the same type or may be of different types. For example, the pipette heads may be air displacement pipettes and/or positive displacement pipettes. In some instances, the fluid handling system may be capable of picking up and/or removing one or more pipette tip. The pipette tips may be individually added or removed from the pipette head. The pipette head may transfer the pipette tip from a first location to a second location. A pipette tip may be capable of connecting to and forming a fluid-tight seal with a pipette head or screwing into it or attaching in other ways. A sample or other fluid may be aspirated and/or dispensed by the pipette tip.

The pipette tip may have an interior surface and an exterior surface. The pipette tip may have a first end and an opposing second end. In some embodiments, both the first and second ends may be open. In some embodiments, the first end may have a diameter that is greater than the diameter of the second end. The pipette tip may or may not be coated with reagents and/or capturing binders such as antibodies. In some instances, an interior surface of the pipette tip may be coated with a reagent and/or capturing binders. A chemical reaction may take place within the pipette tip. The chemical reaction may take place within the pipette tip while the tip is attached to a pipette head, or when the tip is separated from the pipette head. Alternatively, chemical reactions may take place within one or more vessel. The pipette may deliver a sample or other fluid to, or aspirate a sample or other fluid from, a vessel. The pipette tip may be capable of being at least partially inserted into a vessel.

The pipettor may be utilized to transfer a sample or other fluid within the device. The pipettor may assist with the preparation of a sample. The pipettor may assist with the running of a chemical reaction.

The sample processing device may be capable of performing at least one sample preparation step and/or running one or more, two or more, three or more, four or more, five or more, six or more, seven or more, eight or more, nine or more, ten or more, twenty or more, thirty or more, or fifty or more chemical reactions. The device may be capable of performing one or more, two or more, three or more, four or more, five or more, six or more, seven or more, eight or more, nine or more, ten or more, twenty or more, thirty or more, or fifty or more different types of assays. These may occur simultaneously and/or in sequence. The sample preparation and/or chemical reactions that may occur may be governed by protocols that may be individualized to a subject's needs and/or sent back and forth from a server and/or stored or inputted locally. The subject's needs may be based on a prescription or instructions that the subject has received from a health care professional. The device may be configured to accommodate a wide range of sample preparation and/or chemical reactions.

The sample processing device 300 may include one or more detector 360 which may be capable of detecting one or more signal relating to the sample. The detector may be able to detect all emissions from the electromagnetic spectrum. Alternatively the detector may be able to detect a selected range of emission from the electromagnetic spectrum. For example, an optical detector may detect an optical signal relating to a chemical reaction that had taken place on the device. An electrical property sensor or other sensor may detect the voltage, current, impedance, resistance, or any other electrical property of a sample. A temperature sensor may determine the temperature of a thermal block, upon which a sample may rest. A sensor may determine the speed of a centrifuge. A sensor may determine the position, velocity, and/or acceleration of a pipette and/or the successful execution of a protocol.

One or more detectable signal may be detected by a detector 360. The detectable signal can be a luminescent signal, including but not limited to photoluminescence, electroluminescence, chemiluminescence, fluorescence, phosphorescence or any emission from the electromagnetic spectrum. In some embodiments, one or more label may be employed during a chemical reaction. The label may permit the generation of a detectable signal. Methods of detecting labels are well known to those of skill in the art. Thus, for example, where the label is a radioactive label, means for detection may include a scintillation counter or photographic film as in autoradiography. Where the label is a fluorescent label, it may be detected by exciting the fluorochrome with the appropriate wavelength of light and detecting the resulting fluorescence by, for example, microscopy, visual inspection, via photographic film, by the use of electronic detectors such as digital cameras, charge coupled devices (CCDs) or photomultipliers and phototubes, or other detection device. In some instances, cameras may utilize CCDs, CMOS, may be lensless cameras (e.g., Frankencamera), open-source cameras, or may utilize or any other visual detection technology known or later developed in the art. In some embodiments, imaging devices may employ 2-d imaging, 3-d imaging, and/or 4-d imaging (incorporating changes over time). Similarly, enzymatic labels are detected by providing appropriate substrates for the enzyme and detecting the resulting reaction product. Finally, simple colorimetric labels are often detected simply by observing the color associated with the label. For example, conjugated gold often appears pink, while various conjugated beads appear the color of the bead.

In some embodiments, an imaging unit may be provided. Examples of imaging units may include any of the detectors and/or optical detection devices as described elsewhere herein. For example, imaging units may be cameras which may utilize CCDs, CMOS, may be lensless cameras (e.g., Frankencamera), open-source cameras, or may utilize or any other visual detection technology known or later developed in the art. An imaging unit may capture static images and/or may capture moving images. For example, the imaging unit may capture a series of digital images. An imaging unit may capture video images. An imaging device may be a camera or a sensor that detects and/or records electromagnetic radiation and associated spatial and/or temporal dimensions.

In one example, the imaging unit may capture one or more digital image of a sample. For example, the imaging unit may capture an image of a tissue sample. The picture of the tissue sample may be transmitted to a pathologist or other health care professional. Analysis and/or oversight may occur for the image of the tissue sample. Analysis and/or oversight may occur on-board or remotely, by a health care professional or a software program. In other examples, the imaging unit may capture images of a sample, and/or any form of preparation of the sample such as chemical reactions or physical processing steps occurring with the sample. For example, a video may be taken of a chemical reaction. Any description herein of data may also apply to data representative of images, and vice versa.

Imaging may be used to, e.g., detect, examine, identify, characterize, and quantify cells in a sample, such as in, e.g., a blood sample, a urine sample, biopsy tissue, or other sample. Such use of imaging and other techniques may be termed “cytometry.” Cytometry includes observations and measurements of cells, such as red blood cells, platelets, white blood cells, including qualitative and quantitative observations and measurements of cell numbers, cell types, cell surface markers, internal cellular markers, and other characteristics of cells of interest. Where a biological sample includes or is a blood sample, the sample may be divided into portions, and may be diluted (e.g., to provide greater volume for ease of handling, to alter the density or concentration of cellular components in the sample to provide a desired diluted density, concentration, or cell number or range of these, etc.). The sample may be treated with agents which affect coagulation, or may be treated or handled so as to concentrate or precipitate sample components (e.g., ethylene diamine tetraacetic acid (EDTA) or heparin may be added to the sample, or the sample may be centrifuged or cells allowed to settle). A sample may be treated by adding dyes or other reagents which may react with and mark particular cells or particular cellular components. For example, dyes which mark cell nuclei (e.g., hematoxylin dyes, cyanine dyes, drag dyes such as Draq5, and others); dyes which mark cell cytoplasm (e.g., eosin dyes, including fluorescein dyes, and others) may be used separately or together to aid in visualization, identification, and quantification of cells. More specific markers, including antibodies and antibody fragments specific for cellular targets, such as cell surface proteins, intracellular proteins and compartments, and other targets, are also useful in cytometry.

Biological samples may be measured and analyzed by cytometry using optical means, including, for example, photodiode detectors, photomultipliers, charge-coupled devices, laser diodes, spectrophotometers, cameras, microscopes, or other devices which measure light intensity (of a single wavelength, of multiple wavelengths, or of a range, or ranges, of wavelengths of light), form an image, or both. A field of view including a sample may be imaged, or may be scanned, or both, using such detectors. A biological sample may be measured and analyzed by cytometry prior to processing, dilution, separation, centrifugation, coagulation, or other alteration. A biological sample may be measured and analyzed by cytometry during or following processing, dilution, separation, centrifugation, coagulation, or other alteration of the sample. For example, a biological sample may be measured and analyzed by cytometry directly following receipt of the sample. In other examples, a biological sample may be measured and analyzed by cytometry during or after processing, dilution, separation, centrifugation, coagulation, or other alteration of the sample.

For example, a blood sample may be prepared for cytometry by sedimentation or centrifugation. A sedimented or pellet portion of such a sample may be resuspended in a buffer of choice prior to cytometric analysis (e.g., by aspiration, stirring, sonication, or other processing). A biological sample may be diluted or resuspended with water, or with a saline solution, such as a buffered saline solution prior to cytometric analysis. A solution used for such dilution or resuspension may or may not include a fixative (e.g., formaldehyde, paraformaldehyde, or other agent which cross-links proteins). A solution used for such dilution or resuspension may provide an osmotic gradient between the surrounding solution and the interior, or an interior compartment, of cells in the sample, effective that the cell volume of some or all cells in the sample is altered. For example, where the resulting solution concentration following dilution is less than the effective concentration of the interior of a cell, or of an interior cell compartment, the volume of such a cell will increase (i.e., the cell will swell). A biological sample may be diluted with a solution which may or may not include an osmoticant (such as, for example, glucose, sucrose, or other sugar; salts such as sodium, potassium, ammonium, or other salt; or other osmotically active compound or ingredient). In embodiments, an osmoticant may be effective to maintain the integrity of cells in the sample, by, for example, stabilizing or reducing possible osmotic gradients between the surrounding solution and the interior, or an interior compartment, of such cells. In embodiments, an osmoticant may be effective to provide or to increase osmotic gradients between the surrounding solution and the interior, or an interior compartment, of such cells, effective that the cells at least partially collapse (where the cellular interior or an interior compartment is less concentrated than the surrounding solution), or effective that the cells swell (where the cellular interior or an interior compartment is more concentrated than the surrounding solution).

For example, a biological sample may be measured or analyzed following dilution of the sample with a solution including dyes. For example, a biological sample may be measured or analyzed following dilution of a portion of the sample with a solution including antibodies or antibody fragments. For example, a biological sample may be measured or analyzed following dilution of the sample with a solution including particles. Particles added to a biological sample may serve as standards (e.g., may serve as size standards, where the size or size distribution of the particles is known, or as concentration standards, where the number, amount, or concentration of the particles is known), or may serve as markers (e.g., where the particles bind or adhere to particular cells or types of cells, to particular cell markers or cellular compartments, or where the particles bind to all cells in a sample).

For example, a biological sample may be measured or analyzed following processing which may separate one or more types of cells from another cell type or types. Such separation may be accomplished by gravity (e.g., sedimentation); centrifugation; filtration; contact with a substrate (e.g., a surface, such as a wall or a bead, containing antibodies, lectins, or other components which may bind or adhere to one cell type in preference to another cell type); or other means. Separation may be aided or accomplished by alteration of a cell type or types. For example, a solution may be added to a biological sample, such as a blood sample, which causes some or all cells in the sample to swell. Where one type of cell swells faster than another type or types of cell, cell types may be differentiated by observing or measuring the sample following addition of the solution. Such observations and measurements may be made at a time, or at multiple times, selected so as to accentuate the differences in response (e.g., size, volume, internal concentration, or other property affected by such swelling) and so to increase the sensitivity and accuracy of the observations and measurements. In some instances, a type or types of cells may burst in response to such swelling, allowing for improved observations and measurements of the remaining cell type or types in the sample.

Observation, measurement and analysis of a biological sample by cytometry may include photometric measurements, for example, using a photodiode, a photomultiplier, a laser diode, a spectrophotometer, a charge-coupled device, a camera, a microscope, or other means or device. Cytometry may include preparing and analyzing images of cells in a biological sample (e.g., two-dimensional images), where the cells are labeled (e.g., with fluorescent, chemiluminescent, enzymatic, or other labels) and plated (e.g., allowed to settle on a substrate) and imaged by a camera. The camera may include a lens, and may be attached to or used in conjunction with a microscope. Cells may be identified in the two-dimensional images by their attached labels (e.g., from light emitted by the labels).

An image of cells prepared and analyzed by a cytometer as disclosed herein may include no cells, one cell, or multiple cells. A cell or cell in an image of a cytometer, as disclosed herein, may be labeled, as disclosed above. A cell or cell in an image of a cytometer, as disclosed herein, may be labeled, as disclosed above, effective to identify the image, and the subject from whom the sample was taken.

Cytometric measurements of cells from samples of blood have been made using devices, systems, and methods embodying features disclosed herein. Cytometric images have been used, for example, to count the numbers of cells (e.g., providing the number of cells per volume of blood), to determine the sizes and size distribution of cells in the sample (including mean, standard deviation, and other size measures), and to identify cell types based on cell surface markers. Typically, the total concentration of red blood cells and platelets is in the range of about 1-3×10⁶ cells per microliter (e.g., about 2×10⁶ cells per microliter). Cells were allowed to settle on the floor of a channel within the cuvette, allowing an image to be taken of a single focal plane that was sufficient to detect all the cells in the volume within the image area; thus a count of the cells in a single image provided a count of the cells in the volume of blood represented by that image. Since the dimensions of the channel were known, the volume of blood above the area shown in the image allowed accurate calculation of the density of cells within that volume. Volume is also measured by inclusion of known concentrations of beads (the images of which are distinguishable from blood cell images) as indicators; since the concentration of the beads was known, counting the numbers of beads in a field allowed a precise calculation of the volume of sample from which an image was taken.

Optical images included fluorescence images for detecting red, blue and green wavelengths (useful, for example, for detecting and measuring fluorescence from dyes attached to specific cell-surface markers), and darkfield images (useful for detecting cell shape and outlines, and for measuring cell size and volume). Fluorescence images may be used, for example, to identify and quantitate different cell types in the sample. Darkfield images are based on light scattered from the objects in the cuvette, and they provide information regarding the size, shape, and number of objects in the cuvette. Forward scatter measurements were used to quantify cell size. Side scatter measurements were used to determine, identify, and categorize cell morphology.

Data from the images was processed by a controller associated with the sample processing device. The following measurements may be calculated: 1) number of red blood cells in the cuvette; 2) average volume of red blood cells in the cuvette; 3) red blood cell distribution width (RDW) of red blood cells in the cuvette; 4) number of platelets in the cuvette; 5) average volume of platelets in the cuvette; and 6) platelet distribution width of platelets in the cuvette.

Microscopy methods that may be used with devices and systems disclosed herein include but are not limited to bright field, oblique illumination, dark field, dispersion staining, phase contrast, differential interference contrast (DIC), polarized light, epifluorescence, interference reflection, fluorescence, confocal (including CLASS), confocal laser scanning microscopy (CLSM), structured illumination, stimulated emission depletion, electron, scanning probe, infrared, laser, widefield, light field microscopy, lensless on-chip holographic microscopy, digital and conventional holographic microscopy, extended depth-of-field microscopy, optical scatter imaging microscopy, deconvolution microscopy, defocusing microscopy, quantitative phase microscopy, diffraction phase microscopy, confocal Raman microscopy, scanning acoustic microscopy and X-ray microscopy. Magnification levels used by microscopy may include, as nonlimiting examples, up to 2×, 5×, 10×, 20×, 40×, 60×, 100×, 100×, 1000×, or higher magnifications. Feasible magnification levels will vary with the type of microscopy used. For example, images produced by some forms of electron microscopy may involve magnification of up to hundreds of thousands of times. Multiple microscopy images may be recorded for the same sample to generate time-resolved data, including videos. Individual or multiple cells may be imaged simultaneously, by parallel imaging or by recording one image that encompasses multiple cells. A microscopic objective may be immersed in media to change its optical properties, such as through oil immersion. A microscopic objective may be moved relative to the sample by means of a rotating CAM to change the focus. Cytometry data may be processed automatically or manually, and may further include analyses of cell or tissue morphology, such as by a pathologist for diagnostic purposes.

The microscopic objective can be finely positioned to focus the image via an actuator, such as by a cam connected to a motor. The objective may be focused on one or more planes of the sample. Focusing may be automated by image analysis procedures by computing the image sharpness of digital images among other methods.

Cell counting can be performed using cytometry, e.g., imaging with or without microscopy. In situations where the subjects may be bright-field illuminated, the preferred embodiment is to illuminate the subjects from the front with a white light and to sense the cells with an imaging sensor. Subsequent digital processing will count the cells. Where the cells are infrequent or are small, the preferred embodiment is to attach a specific or non-specific fluorescent marker, and then illuminate the subject field with a laser or other suitable light source. Confocal scanning imaging may be used. In embodiments, up to 500 or 1000 cells of any given type may be counted. In other embodiments, various numbers of cells of any given type may be counted, including but not limited to more than or equal to about 1 cell, 5 cells, 10 cells, 30 cells, 50 cells, 100 cells, 150 cells, 200 cells, 300 cells, 500 cells, 700 cells, 1000 cells, 1500 cells, 2000 cells, 3000 cells, 5000 cells. Cells may be counted using available counting algorithms. Cells can be recognized by their characteristic fluorescence, size and shape.

In some microscopy embodiments, brightfield illumination may be achieved by the use of a white light source along with a stage-condenser to create Koehler illumination. Brightfield images of cells, which may detect properties similar to that of forward scattering in flow cytometry, can reveal cell size, phase-dense material within the cells and colored features in the cell if the cells have been previously stained. In one example embodiment, the Wright-Giemsa staining method can be used to stain human whole blood smear. Brightfield imaging shows characteristic patterns of staining of human leukocytes. The characteristically shaped red cells can also be identified in these images.

In some microscopy embodiments, darkfield imaging may be achieved by the use of a ringlight based illumination scheme, or other epi- or trans-darkfield illumination schemes available. Darkfield imaging may, for example, be used to determine light scattering properties of cells, equivalent to side scatter in flow cytometry, such as when imaging human leukocytes. The internal and external features of the cell which scatter more light appear brighter and the features which scatter lesser amounts of light appear darker in a darkfield image. Cells such as granulocytes have internal granules of size range (100-500 nm) which can scatter significant amount of light and generally appear brighter in darkfield images. Furthermore, the outer boundary of any cell may scatter light and may appear as a ring of bright light. The diameter of this ring may directly give the size of the cell. Microscopy methods may additionally be used to measure cell volume. For example, red blood cell volume may be measured. To increase accuracy, red blood cells may be transformed into spheres through the use of anionic or zwitterionic surfactants, and dark field imaging used to measure the size of each sphere, from which cell volumes may be calculated.

In some microscopy embodiments, small cells or formed elements which may be below the diffraction-limited resolution limit of the microscope, may be labeled with fluorescent markers; the sample may be excited with light of appropriate wavelength and an image may be captured. The diffraction pattern of the fluorescent light emitted by the labeled cell may be quantified using computer analysis and correlated with the size of the cell. The computer programs used for these embodiments is described elsewhere herein. To improve the accuracy of this method, the cells may be transformed into spheres by the use of anionic and zwitterionic surfactants.

Cell imaging may be used to extract one or more of the following kinds of information for each cell (but is not limited to the following): Cell size; Quantitative measure of cell granularity or light scattering (also popularly called side scatter, based on flow cytometry parlance); Quantitative measure of fluorescence in each spectral channel of imaging, after compensating for cross-talk between spectral channels, or intracellular distribution pattern of fluorescent or other staining; Shape of the cell, as quantified by standard and custom shape attributes such as aspect ratio, Feret diameters, Kurtosis, moment of inertia, circularity, solidity etc.; Color, color distribution and shape of the cell, in cases where the cells have been stained with dyes (not attached to antibodies or other types of receptor); Intracellular patterns of staining or scattering, color or fluorescence that are defined as quantitative metrics of a biological feature such as morphology, for example density of granules within cells in a darkfield image, or the number and size of nucleolar lobes in a Giemsa-Wright stained image of polymorphonuclear neutrophils etc.; Co-localization of features of the cell revealed in images acquired in different channels; Spatial location of individual cells, cellular structures, populations of cells, intracellular proteins, ions, carbohydrates and lipids or secretions (such as to determine the source of secreted proteins).

A wide range of cell-based assays can be designed to use the information gathered by cytometry. For example, an assay for performing a 5-part leukocyte differential may be provided. The reportables in this case may, for example, be number of cells per microliter of blood for the following types of leukocytes: monocytes, lymphocytes, neutrophils, basophils and eosinophils. Reportables may also be used to classify leukocyte differentiation, or identify T and B-cell populations.

Fluorescence microscopy generally involves labeling of cells or other samples with fluorescent labels, described in more detail below. Microscopic imaging of fluorescently labeled samples may gather information regarding the presence, amounts, and locations of the target that is labeled at a given moment in time or over a period of time. Fluorescence may also be used to enhance sensitivity for detecting cells, cellular structures, or cellular function. In fluorescence microscopy, a beam of light is used to excite the fluorescent molecules, which then emit light of a different wavelength for detection. Sources of light for exciting fluorophores are well known in the art, including but not limited to xenon lamps, lasers, LEDs, and photodiodes. Detectors include but are not limited to PMTs, CCDs, and cameras.

Spectroscopy includes any and all assays that produce luminescence or change light (e.g., color chemistry). These may include one or more of the following: spectrophotometry, fluorimetry, luminometry, turbidimetry, nephelometry, refractometry, polarimetry, and measurement of agglutination.

Spectrophotometry refers to measuring a subject's reflection or transmission of electromagnetic waves, including visible, UV, and infrared light. Spectrophotometry may, for example, be used to determine nucleic acid concentrations in a sample, such as by measuring absorbance at a wavelength of about 260 nm, to determine protein concentration by measuring absorbance at a wavelength of about 280 nm, and/or to determine salt concentration by measuring absorbance at a wavelength of about 230 nm.

Other examples of spectrophotometry may include infrared (IR) spectroscopy. Examples of infrared spectroscopy include near-infrared spectroscopy, far-infrared spectroscopy laser-Raman spectroscopy, Raman confocal laser spectroscopy, Fourier Transform infrared spectroscopy, and any other infrared spectroscopy technique. Frequencies of less than about 650 cm-1 are typically used for far-infrared spectroscopy, frequencies greater than about 4000 cm-1 are typically used for near-infrared spectroscopy, while frequencies between about biomedical applications, including in screening and diagnosis of cancer, arthritis, and other diseases, determining chemical compositions of biological fluids, determining septic state, and others. IR spectroscopy may be used on solid samples, such as tissue biopsies, cell cultures, or Pap smears; or on liquid samples, such as blood, urine, synovial fluid, mucus, and others. IR spectroscopy may be used to differentiate between normal and cancerous cells as described in U.S. Pat. No. 5,186,162, herein incorporated by reference. IR spectroscopy may also be used on blood samples to detect markers for cancers of various solid organs. IR spectroscopy may also be used to determine cellular immunity in patients, such as to diagnose immunodeficiencies, autoimmune disorders, infectious diseases, allergies, hypersensitivity, and tissue transplant compatibility.

IR spectroscopy may be used to determine glucose levels in blood, which is of use for diabetic patients, such as for monitoring insulin response. IR spectroscopy may further be used to measure other substances in blood samples, such as alcohol levels, fatty acid content, cholesterol levels, hemoglobin concentration. IR spectroscopy can also distinguish between synovial fluid from healthy and arthritic patients.

Fluorimetry refers to measuring the light emitted by a fluorescent molecule coupled to a subject upon exciting the fluorescent molecule with incident light. Fluorimetry may use any of the fluorescent molecules, labels, and targets as described for cytometric assays above. In some embodiments, fluorimetry uses substrate molecules that change in fluorescence based on an enzymatic activity, such as converting NAD+ to NADH or vice versa or producing beta-galactosidase from a precursor molecule. Fluorimetry may be used with a polarized excitation source to measure fluorescence polarization or anisotropy of a subject, which may provide information about the size and/or binding state.

Colorimetry refers to measuring the transmissive color absorption of a subject, preferably by backlighting the subject with white light with the result sensed by an imaging sensor. Examples include some assays that use oxidases or peroxidases combined with a dye that becomes colored in the presence of hydrogen peroxide. One method that measures peroxidase activity in whole cell suspensions of human white blood cells is disclosed in Menegazzi, et al., J. Leukocyte Biol 52: 619-624 (1992), which is herein incorporated by reference in its entirety. Such assays may be used to detect analytes that include but are not limited to alcohols, cholesterols, lactate, uric acid, glycerol, triglycerides, glutamate, glucose, choline, NADH. Some of the enzymes that may be used include horseradish peroxidase, lactoperoxidase, microperoxidase, alcohol oxidase, cholesterol oxidase, NADH oxidase. Other nonlimiting examples of colorimetric assays include dye-based assays to determine protein concentration, such as Bradford, Lowry, biureat, and Nano-orange methods. The pH of a sample may also be determined by colorimetric assays with indicator dyes, including but not limited to phenolphtalein, thymolphtalein, alizarin Yellow R, indigo carmine, m-cresol purple, cresol red, thymol blue, xylenol blue, 2,2′,2″,4,4′-pentamethoxytriphenyl carbinol, benzopurpurin 4B, metanil yellow, 4-phenylazodiphenylamine, malachite green, quinaldine red, orange IV, thymol blue, xylenol blue, and combinations thereof.

Luminometry uses no illumination method as the subject emits its own photons. The emitted light can be weak and can be detecting using an extremely sensitive sensor such as a photomultiplier tube (PMT). Luminometry includes assays that produce chemiluminescence, such as those using luciferases or some assays using peroxidases.

For turbidimetry, the preferred embodiment for sensing is backlighting the subject with white light with the result sensed by an imaging sensor. For turbidimetry, the reduction of the intensity of the transmitted light is measured. Turbidimetry may be used, for example, to determine a concentration of cells in solution. In some embodiments, turbimetry is measured by nephelometry.

Nephelometry measures the light that is transmitted or scattered after passing through a subject in a suspension, typically a substrate bound to an immunoglobin such as IgM, IgG, and IgA.

Polarimetry measures the polarization of, typically, electromagnetic waves by a subject. Polarimetry assays include circular dichroism, which may provide structural information and light scattering assays, which may provide information about the size and/or shape of the subject. One nonlimiting example of light scattering assays uses dynamic light scattering (DLS). Subjects for these assays do not require labeling.

The sample processing device 300 may have a processor 330 that may provide instructions to one or more components of the device. The processor may act as a controller that may instruct one or more component of the device. For example, the processor may provide an instruction to a pipette to aspirate or dispense a fluid. The processor may provide an instruction that controls the temperature of a heater (which may optionally heat and/or cool the device). The processor may provide an instruction to an optical detector to detect one or more signal. The processor may also receive instructions and/or collected data. For example, a processor may act in accordance with one or more protocol. The protocol may be provided on board the device or may be provided from a source external to the device. The processor may also receive data regarding signals detected by the device. The processor may or may not analyze signals that have been detected by the device. The processor may or may not compare one or more detected signal with a threshold value.

A communication module 340 may be provided on the device 300. A communication unit may be part of a laboratory or set-up which includes the device.

FIG. 4 shows an example of a sample collection, processing, and analysis method. One or more of the following steps may occur in such a method. The order of the steps may be modified, or one or more step may be optional or may be substituted by another step. Steps illustrated in FIG. 4 by boxes numbered from 400 to 440 represent steps which may be considered pre-analytic steps. Pre-analytic steps include sample collection, verification, preparation, including oversight, calibration, running of controls, acquisition of raw data, and other steps as shown in the figure and as disclosed herein. In embodiments, oversight of pre-analytic steps may be performed at one or more times before, during, and after sample collection and testing, or may be continuous throughout a period or periods before, during, and after sample collection and testing. Steps illustrated in FIG. 4 by boxes numbered from 450 to 460 represent steps which may be considered analytic steps. Analytic steps include analysis of data received from a device at a sample collection site, as indicated in the figure and as disclosed herein. In embodiments, oversight of analytic steps may be performed at one or more times before, during, and after analysis, or may be continuous throughout a period or periods before, during, and after analysis. Steps illustrated in FIG. 4 by boxes numbered from 470 to 480 represent steps which may be considered post-analytic steps. Post-analytic steps include review of the analysis of data, comparison with controls, calibrations, device and sample identification and information, review of report generation and of the report generated for a particular test, and other steps as indicated in the figure and as disclosed herein. In embodiments, oversight of post-analytic steps may be performed at one or more times before, during, and after post-analysis, or may be continuous throughout a period or periods before, during, and after post-analysis. Methods disclosed herein, and devices and systems useful in the practice of such methods, may be, or may be used with, or may be part of, a laboratory automation system (LAS), or a laboratory information system (LIS), or an electronic medical record system (EMR). In embodiments of the methods, systems, and devices disclosed herein, a method, system or device as disclosed herein may be integrated with a LAS, a LIS, or an EMR. In embodiments, an EMR may be integrated with an LAS, a LIS, and methods, systems, or devices as disclosed herein.

The method may include collecting a sample from a subject 400, preparing the sample for running a chemical reaction 410, permitting a chemical reaction with one or more reagent 420, detecting a signal relating to the sample, chemical reaction, and/or component of the device 430, pre-processing the detected signals without performing analysis, analyzing the data 450, generating a report based on the data 460, transmitting a report 470, providing the report to a health care professional 480, and/or displaying a report on the device and/or screen or other display device.

One or more of these steps may be provided by any device or entity. The demarcations illustrated in the figures are provided by way of example only, and are in no way limiting. For example, a sample may be collected 400 external to a device 490. Alternatively, the sample may be collected directly at the device, or may be collected by the device. This may occur at a sample collection site. The sample prep 410, chemical reaction 420, or signal detection steps 430, may be performed by the device 490.

In some embodiments, a sample may be prepared for a subsequent qualitative and/or quantitative evaluation. Such a sample preparation for evaluation step may include one or more of the sample prep 410, chemical reaction 420, and/or signal detection 430 steps. In some embodiments, a sample may be processed by receiving the sample 400, and/or preparing the sample for a subsequent qualitative and/or quantitative evaluation, to yield data necessary for the subsequent qualitative and/or quantitative evaluation. Sample processing may also include transmitting the data from the device. In some instances, the data may be transmitted to a health care professional of an authorized analytical facility.

One, two or all these of these steps may take place, and one, two, or all of the steps that take place may occur at the device at a sample collection site. Alternatively, they may take place at another entity, such as a laboratory. The point of service site near or on the body (such as the home) of the subject may be a laboratory or sample collection site.

Data collected by the device may be in a raw state. This may include signals detected at the device. The data may optionally undergo pre-processing 440. Data pre-processing does not perform actual data analysis or comparison with any threshold values. Data pre-processing may involve modifying the format of data. In some instances, data pre-processing may occur at a device 490 at a sample collection site. Then the pre-processed data may be transmitted to a laboratory. Alternatively, data pre-processing 440 may occur at a laboratory 492. Raw data may be sent from a device to the laboratory where pre-processing may occur. Alternatively, no pre-processing occurs within the method.

Examples of raw data include, but are not limited to, the following: light data, including light intensity, wavelength, polarization, and other data regarding light, e.g., output from optical detectors such as photomultiplier tubes, photodiodes, charge-coupled devices, luminometers, spectrophotometers, cameras, and other light sensing components and devices, including absorbance data, transmittance data, turbidity data, luminosity data, wavelength data (including intensity at one, two, or more wavelengths or across a range of wavelengths), reflectance data, refractance data, birefringence data, polarization, and other light data. Light data may provide information about the presence, number, or other characteristic of an analyte, cell, particle, or other subject of interest in a sample, tissue, container, or field of view. Light data may provide information about the presence, progress, or completion of a chemical reaction or physical process.

Raw data includes image data, e.g., data from digital or analog cameras, including images of tissues, including tissue slices and biopsy samples; images of cells, particles, crystals, or other elements which may be present in a sample; images may include two-dimensional images of cells particles, or crystals, such as fluorescently labeled or chemiluminescent cells; two-dimensional images of light scattered by cells, particles, or crystals; two-dimensional images of cells, particles or crystals taken using phase contrast, bright-field, dark-field, interference contrast, or other technique; two-dimensional images of cells in a tissue slice or other histological specimen, where the cells may, or may not be stained. Images may include three-dimensional images of cells particles, or crystals, such as fluorescently labeled or chemiluminescent cells; three-dimensional images of light scattered by cells, particles, or crystals; three-dimensional images of cells, particles or crystals taken using phase contrast, bright-field, dark-field, interference contrast, or other technique; three-dimensional images of cells in a tissue slice or other histological specimen, where the cells may, or may not be stained. Raw data includes cell counts, cell shape, numbers of stained or labeled cells, and intensity of staining or labeling.

Raw data includes temperature measurements, duration measurements, pH measurements, ion and other analyte measurements, particle counts, hematocrit measurements, and other measurements of chemical and physical characteristics of a sample, or of sample constituents. Raw data includes data measuring or indicating the progress of a chemical reaction or physical change, including color changes due to enzymatic action on the product of a chemical reaction. Such raw data provides data from chemical assays, including measurements of light emitted or absorbed during or following chemical reactions, binding reactions, competition reactions, and other reactions and assays. Such raw data may provide a direct measure of the chemical reaction or assay, or further processing or analysis based on the raw data may be required to provide a desired measurement.

Raw data may be pre-processed by a device prior to transmission to a laboratory location. In embodiments, raw data is transmitted from a sample collection location to a laboratory location without pre-processing.

Data analysis may occur 450 in accordance with an embodiment of the invention. Data analysis may include a subsequent qualitative and/or quantitative evaluation of a sample. The quantitative and/or qualitative analysis may involve a determination of clinical relevance of the biological sample or lack thereof. Data analysis may include one or more comparison of the data with a threshold value. Said comparison may be used to determine the presence or concentration of one or more analyte, or may be useful for analytical methods and/or pathological analysis described elsewhere herein. Data analysis may occur at a laboratory 492. In some embodiments, the laboratory may be a certified laboratory. The data that may be analyzed may be raw data or pre-processed data. A device may process a sample without analyzing the sample. Data analysis does not occur on the device in this scenario.

The data that may be analyzed may be provided from a device 490 or may be modified at the laboratory 492 or other entity prior to being analyzed. In another embodiment of the invention, the data analysis 450 may occur on the device without occurring at a laboratory. Alternatively, data analysis may occur on both the device and at the laboratory or the device may be the laboratory. The analysis may occur at a point of service location, such as a home, office, doctor's office/hospital, retailer site, or other point of service location. Any description herein of a laboratory location or other location, may apply to any other point of service location described elsewhere herein.

A report may be generated 460 based on the data. A report may be based on analyzed data 450 or may be based on data in its raw or pre-processed form. The report may be generated based on a qualitative and/or quantitative evaluation of the sample. The report may be generated at a laboratory 492, such as an authorized analytical facility. Alternatively, the report can be generated at the device, or by any other entity. The report may be transmitted 470. The report may be transmitted by the same entity that generated the report.

In some embodiments, a display (such as a screen) or sensors in a device may conduct imaging externally. For example, the device may be capable of conducting MRI, ultrasound, or other scans.

The sample preparation and/or chemical reaction may occur in response to one or more instructions. The instructions may be stored locally on the device or may be provided from an external source. In some embodiments, the external source is a laboratory. In some embodiments, the sample preparation and/or chemical reaction procedures may be self-educated. For example, they may be capable of picking up different ways of preparing a sample and/or making it ready for analysis. In some embodiments, the sample preparation procedures may be able to self adjust to utilize various sample preparation techniques given a set of parameters. The sample preparation adjustment or maintenance may or may not rely on signals detected relating to a sample, and/or to parameters and/or instructions provided by an operator. The sample preparation procedures may be self-learning. One or more controller that may provide instructions to conduct a sample preparation and/or chemical reaction may be capable of self-learning.

The adjustments may be made in response to new instructions that may be generated locally on the device or that may be provided from the external source. For example, new instructions may be updated and/or pushed down from the external source. There may be a dynamic process in which the sample preparation and/or chemical reaction and/or physical processing steps are performed in accordance with changeable instructions. Any description herein relating to a sample preparation and/or chemical reaction may also include any physical processing steps.

One or more signal may be detected 430 from the device. The signal may be detected after a sample preparation step has been done and/or after a chemical reaction and/or physical processing step has taken place. In some embodiments, one or more signal may be detected even if no sample preparation and/or chemical reaction has taken place on the sample. The signals may be based on a reading of a sample that may or may not have undergone an assay. The signals may be based on a measurement relating to the device.

In some instances, one or more additional sample preparation steps may occur. For instance, an additional sample preparation for qualitative and/or quantitative evaluation may occur. Such preparation may be made based on at least one of: prior preparation of the biological sample and/or analysis of the data by the health care professional. Reflex testing may occur based on earlier results. The reflex testing may occur in an automatic and dynamic manner before, during, or after the test/analyses. Earlier evaluation may yield further testing, which may be automated.

Optionally, data may undergo pre-processing 440. Raw data of detected signals may or may not undergo pre-processing. Pre-processing may affect the format of the raw data. For example, the pre-processing may normalize a format of the data. The pre-processing may put the data into a desired form. Pre-processing may occur without performing any analysis of the data. In some embodiments, the pre-processing may alter the form of the data without altering the content of the data. In some instances, pre-processing does not compare the data with any threshold values or perform any valuation judgments.

The data may be analyzed 450, as described elsewhere herein. Data analysis may include a subsequent qualitative and/or quantitative evaluation of a sample. Optionally, a report may be generated based on the raw data, pre-processed data, or the analyzed data. The report and/or the data may be transmitted to a health care professional. A software system may perform chemical analysis and/or pathological analysis, or these could be distributed amongst combinations of lab, clinical, and referenced/contracted specialty personnel (e.g., lab and John's Hopkins laboratory for specialty experts of some diseases or to engage them as part of/in a certified laboratory).

In some embodiments, the report may be reviewed before being transmitted to the health care professional. In some instances, the data may be reviewed before or after the report is generated. The review may occur by one or more pathologist or other qualified person. The pathologist may be associated with a laboratory 492. The pathologist may or may not be physically located at the laboratory facility. The pathologist may be employed by the laboratory. For an authorized analytical facility, oversight may be provided via a regulatory body. In some embodiments, the laboratory may be a CLIA certified laboratory. A board certified entity (which may include board-certified personnel) may review the data/reports and provide a measure of quality control and verification. In some embodiments, the board certified entity may include one or more pathologist.

In some embodiments, a device may be a certified device. The device may be under the oversight of a regulatory body.

In embodiments of the devices, systems, and methods disclosed herein, the handling of a sample may comprise one of three stages: a first stage which may be termed a “pre-analysis” stage; a second stage which may be termed an “analysis” stage; and a third stage which may be termed a “post-analysis” stage. In embodiments, a pre-analysis stage may include such actions and steps as, e.g., sample collection, sample preparation, sample testing, detection of a signal from a sample or observation or imaging of a sample; data pre-processing (if any), and other actions and steps prior to analysis of data obtained regarding a sample. For example, a pre-analytic action may include initiation of a test, and may include contacting a sample with a reagent, detection of the amount of light emitted from, or the amount of light absorbed by, a sample following contact with a reagent, or other such action or step. In embodiments, an analysis stage may include such actions and steps as, e.g., analysis of data obtained regarding a sample, generation of a report regarding the sample and its analysis, and other actions and steps regarding the analysis of data obtained regarding a sample. For example, an analytic action or step may include correcting raw data based on device environmental data and/or calibrations specific for the device or reagents used to examine the sample; calculation of a value, e.g., a concentration value, a hematocrit value, a volume of a cell, or other value; determination of a type or types of cells, particles, or other subject in a sample; or other step or action. In embodiments, a post-analysis stage may include such actions and steps as, e.g., transmission of a report regarding a sample, contacting or receiving communications from a health care professional or other provider regarding such a report, and other actions and steps subsequent to the analysis of data obtained regarding a sample. For example, a post-analytic action or step may comprise a determination of whether or not a test is accurate, e.g., by comparing outliers, controls, and replicates to the results of an analysis. For example, a post-analytic action or step may comprise highlighting values or results that are outliers or may be a cause for concern (e.g., above or below a normal or acceptable range, or indicative of an abnormal condition), or combinations of results which, together, may indicate the presence of an abnormal condition. Such post-analytic action, communicated to a physician or other health-care provider may better insure that the physician or other health-care provider is made aware of, and cognizant of, possible concerns and may thus be more likely to take appropriate action.

In embodiments of devices, systems and methods disclosed herein, a test of a sample may be performed within a device.

In embodiments of devices, systems and methods disclosed herein, a test of a sample may be initiated within a device, and raw data derived from the sample may be transmitted to a different location, e.g., a laboratory location.

Identifying information and data may identify a particular device, its past history, present status, present condition, environmental information regarding the device and its environs, and other data and information. For example, in embodiments, patient identification may be retained with each sample from beginning to end of sample collection, testing, analysis, and reporting of results. In embodiments, patient identification may be retained with each sample from beginning to end of sample collection, testing, analysis, reporting of results, and billing. Identifying information and data may identify a particular cartridge, its contents (including reagents, disposables, and sample information), its past history, present status, present condition, environmental information regarding the cartridge and its environs, and other data and information. Identifying information and data may identify a particular patient, including a patient's identity, age, sex, medications, medical history, test history, present status, present condition, and other data and information. Identifying information and data may identify a particular sample, its mode of collection, patient derived from, condition (sample volume, whether contacted with heparin, EDTA, filtered, coagulated, whether or not there is an air bubble present, whether a blood sample may have undergone hemolysis, or is lipemic), and other data and information. Identifying information and data may specify an analysis to be performed, or that has been performed, on data from a sample. Identifying information and data may specify post-analytic actions to be performed, such as regarding a report, comparison with other test data or analysis, or other action or step.

Protocols may be updated and may be tailored to specific devices, or environmental conditions within or around the device, e.g., taking into account the specific properties and characteristics of sensors, motors, physical dimensions, and other properties and characteristics of an individual device; taking into account the temperature, humidity, air pressure, position and movement of internal modules or components within the device; condition and status of motors, sensors, or other components; taking into account calibrations of motors, sensors, and other components; and other properties and characteristics. Protocols may be updated and may be tailored to specific reagents and disposables, e.g., taking into account control reagents, calibrations of reagents, the specific properties and characteristics of reagents in a cartridge, of tips in a cartridge, of the temperature of a cartridge, or other characteristic or property. Oversight may comprise oversight during or following analysis of data, and may provide for further testing, or re-testing of a sample or of additional samples from a patient.

Use of protocols that include device-specific information, cartridge-specific information, or other information and data specific for sensors, devices, reagents, and other components and elements of testing of a sample, including calibration and control information, provides for correction and scaling of raw data to insure that values and observations obtained from such raw data is correct, consistent, and reproducible. Such values and observations obtained are reproducible across devices, and over time (e.g., from subsequent samples) allowing for comparison of patient results with group and historical values for better screening, diagnosis and treatment based on test results and analysis. Oversight as disclosed herein provides oversight of the integrity of performance of tests, and of results of tests, including oversight of each sample, oversight of the testing of each sample, oversight of the scaling and calibration of raw data obtained during testing, oversight of test integrity, oversight of use and analysis of data in view of controls, calibrators, replicates, and outliers, oversight of the analysis of data in view of device and reagent environmental and calibration information, oversight of the analysis of test results, oversight of the reporting of test results and analysis, and oversight of post-analytic activity and communications. Device and cartridge information may be retained in the cloud or other network; may be retained on or with each device or cartridge; or may be retained, partially or completely, in both locations.

Devices, systems, methods, and protocols as disclosed herein provide multifunctional capabilities, allowing a single device at a sample collection site to perform multiple tests, including multiple types of tests, on a sample; such test may be run rapidly, requiring only small amounts of sample (e.g., requiring only the amount of blood available from a finger-stick), and may be run reliably and accurately, allowing for reproducibility and reliable comparison across devices and samples. Thus, the devices disclosed herein are multifunctional; the assays they perform are multifunctional; the controls are multifunctional; and the oversight is multifunctional. Multifunctional includes the ability to perform multiple types of assays, including nucleic acid assays, general chemistry assays, cytometry (e.g., cell imaging, flow cytometry) assays, ELISA assays, and others (e.g., as disclosed in U.S. patent application Ser. No. 13/244,947 and in U.S. patent application Ser. No. ______, entitled “Systems and Methods for Multi-Purpose Analysis,” filed Feb. 18, 2013), on a single device and from a single sample.

Devices, systems, methods, and protocols as disclosed herein provide rapid results from testing a small volume sample; such testing and results can be automated, and the rapid provision of such results, e.g. by a laboratory to a health care provider, provides rapid and reliable information for better patient care. Laboratories, such as CLIA-compliant and CLIA-certified laboratories, may have pathologists in place, or readily available, for review and interpretation of results, for further analysis, and for possible recommendations regarding further testing and/or treatment. As disclosed herein, embodiments of devices, systems, methods, including protocols and oversight as disclosed herein may include some or all of the features, elements, and capabilities disclosed, and may include these features, elements, and capabilities in any combination of some or all of such features, elements, and capabilities.

In embodiments, oversight may include at least the following processes: 1) sample collection; 2) receipt of data (e.g., test data, raw data, device data, cartridge data, sample data, patient data, etc.); 3) recognition of a status or problem related to the data); analysis of the status or problem in view of the sample, the test being performed, the device, reagents, etc. performing the test, etc.; and 4) sending instructions to the device, operator, or physician (e.g., general practitioner, pathologist, or other healthcare provider) based on the data and analysis, for further action or modification or cessation of present actions. Such oversight may be intermittent (e.g., occur once or at a few times before, during, or after testing), or may be continuous (on-going during testing, or on-going from a time before testing, and may continue through or beyond the period of testing). In embodiments, oversight may be dynamic oversight, allowing updating of protocols as events occur or data is obtained, to insure proper procedures, proper quality, proper integrity, and proper results from such testing. Such oversight and testing may be “patient-aware”, i.e. may take into account the identity, characteristics (e.g., age, sex, medical history, medication, condition, physician, insurance coverage, or other factor related to the patient for whom the test is being conducted. In this way, the sample and sample analysis may always be linked to the patient throughout the testing process—at the pre-analytical stage, at the analytical stage, and at the post-analytical stage. As disclosed herein, all these tests and analysis may be provided without physically transporting a sample to a laboratory location. Sample collection and processing by the device at a sample collection site, followed by transmission of raw data to the laboratory location allows testing, analysis, and reporting of result to be performed without physically transporting a sample to a laboratory location. The transmission of raw data to the laboratory location provides “digital” transport of a sample or effectively a “virtual sample” obviating a need for physically transporting a sample to a laboratory location. Oversight and control of the operation of the device at the sample collection site by a protocol, provided by the cloud or other network, or directly from a laboratory location, allows for the control and operation of the device by the laboratory. Such control and operation may be by a CLIA-compliant laboratory, which may be a CLIA-certified laboratory.

For example, protocols used by the device in processing the sample may be provided by the laboratory, may be updated by the laboratory, and their proper application may be overseen by the laboratory. Protocols may include instructions and procedures directing the forms of processing and testing to apply to a sample; the order of performing such processing and testing of a sample; the timing of such processing and testing of a sample; the pre-processing, if any, of data obtained by the processing and testing of a sample; the compilation of data, including raw data (and pre-processed data, if any), obtained by the processing and testing of a sample; the transmission of data, including raw data (and pre-processed data, if any), obtained by the processing and testing of a sample, to a laboratory; the receipt of further instructions from a laboratory in response to the data transmitted from the device to the laboratory; further processing or testing of a sample pursuant to any further instructions from a laboratory in response to the data transmitted from the device to the laboratory; and the disposal of sample and other wastes following such processing and testing of a sample.

FIG. 7 shows an example of a lab benefits manager/wholesaler model in accordance with an embodiment of the invention. A retailer 700 (or other point of service), such as a pharmacy, may have one or more sample processing device located at the retailer site. A retailer technician may operate the sample processing device, and may place a cartridge into the device 710. The cartridge may or may not contain a sample from a subject collected at the retailer site.

A laboratory benefit manager 720 may be an LBM as described elsewhere herein. The laboratory benefit manager may be an entity.

A laboratory benefit manager 720 and a wholesaler 730 may be provided within the model. The laboratory benefit manager and the wholesaler may be separate entities. The laboratory benefit manager and the wholesaler may be separate legal entities, corporate entities, corporations, partnerships, organizations, and/or groups of one or more individuals. The laboratory benefit manager and the wholesaler may be housed in different facilities or in the same facility.

A laboratory benefit manager 720 may be in communication with one or more payers 740. The laboratory benefit manager may issue an invoice for a service to the payers. The payer may pay the laboratory benefit manager. For example, the laboratory benefit manager may request a $a (e.g., $28 to provide a numerical example) fee from the payer, who pays the laboratory benefit manager, the $a. The laboratory benefit manager may retain a LBM fee. For example, a $b (e.g., $1 to provide a numerical example) fee may be retained by the laboratory benefit manager.

The laboratory benefit manager 720 may reimburse the retailer 700 for the balance of the amount. For example, the laboratory benefit manager may pay the retailer the remaining $c, (e.g., $27). $c may equal $a minus $b.

The retailer may also have fees associated with the laboratory benefit manager and/or the wholesaler. For example, the retailer may have an agent fee that the retailer may pay the laboratory benefit manager. In one example, the agent fee is $d (e.g., $8 to provide a numerical example). The retailer may also issue a purchase order or pay for a product. For example, the retailer may pay for the purchase or use of the device at the retailer site and/or cartridges. The retailer may pay the laboratory benefit manager. Alternatively, the retailer may pay the wholesaler for the purchase or use of the device and/or cartridges. In one example, the payment for the product may be $e (e.g., $9 to provide a numerical example).

From a laboratory benefit manager perspective, there may be a financial benefit to following the model. For example, the laboratory benefit manager may receive an LBM fee based on the device use. For example, the LBM fee may be $b per transaction. The laboratory benefit manager may also receive an agent fee from the retailer. For example, the laboratory benefit manager may receive an $d admin fee. In some instances, the laboratory benefit manager may also receive a product fee from the retailer. For example, the laboratory benefit manager may receive a $e product fee.

From a retailer perspective, there may be financial benefit to following the model. For example, the retailer may receive a service income of $c. The service income may be provided through the laboratory benefit manager. The laboratory benefit manager may provide the service income based on a payment received from a payer. The laboratory benefit manager may subtract an LBM fee from the amount received from the payer, and may pass the rest on to the retailer as a service income. In additional embodiments, the laboratory benefit manager may also subtract a professional fee, which may be provided to a health care professional or other entity, with the remainder of the balance going to the retailer as a service income. Thus, as shown in FIG. 7, the total revenue may be provided from a $c service income. Costs to the retailer may include an administration fee (e.g., the $d fee shown), and/or a product fee (e.g., the $e fee shown). The costs may be about $f (e.g., $17 to provide a numerical example). $f may equal $d plus $e. The costs to the retailer may be lower than the service income. For example, a $g (e.g., $10 to provide a numerical example) gross margin is illustrated for the retailer. In some instances, $g=$c minus $f.

The table below illustrates examples of the model.

P&L Impacts Retailer Service Income $c Total Revenue $c COGS $f ($d admin fee + $e product cost) Gross Margin $g

Any of the dollar amounts are provided by way of example only and shall not be construed as limiting. Any numerical value may be inserted for the various dollar values.

The verification may employ a video camera and/or a microphone that may capture additional visual and/or audio information. The verification may include comparing the subject's movements (e.g., gait), or voice.

The verification may include entering personal information related to the subject, such as the subject's name, insurance policy number, answers to key questions, and/or any other information. The verification may include collecting one or more biometric read-out of the subject. For example, the verification may include a fingerprint, handprint, footprint, retinal scan, temperature readout, weight, height, audio information, electrical readouts, or any other information. The biometric information may be collected by the device. For example, the device may have a touchscreen upon which the subject may put the subject's palm to be read by the device. The touchscreen may be capable of scanning one or more body part of the subject, and/or receiving a temperature, electrical, and/or pressure readout from the subject. Alternatively, the device may receive the biometric information from other devices. For example, the device may receive the subject's weight from a scale that may be separate from the device. The information may be sent directly from the other devices (e.g., over wired or wireless connection) or may be entered manually.

The verification may also include information based on a sample collected from the subject. For example, the verification may include a genetic signature of the subject. When the sample is provided to the device, the device may use at least part of the sample to determine the genetic signature of the subject. For example, the device may perform one or more nucleic acid amplification step and may determine key genetic markers for the subject. This may form the subject's genetic signature. The subject's genetic signature may be obtained prior to, concurrently with, or after processing the sample on the device. The subject's genetic signature may be stored on one or more data storage unit. For example, the subject's genetic signature may be stored in the subject's electronic medical records. The subject's collected genetic signature may be compared with the subject's genetic signature already stored in the records, if it exists. Any other unique identifying characteristic of the subject may be used to verify the subject's identity.

Methods for the amplification of nucleic acids, including DNA and/or RNA, are known in the art. Amplification methods may involve changes in temperature, such as a heat denaturation step, or may be isothermal processes that do not require heat denaturation. The polymerase chain reaction (PCR) uses multiple cycles of denaturation, annealing of primer pairs to opposite strands, and primer extension to exponentially increase copy numbers of the target sequence. Denaturation of annealed nucleic acid strands may be achieved by the application of heat, increasing local metal ion concentrations (e.g. U.S. Pat. No. 6,277,605), ultrasound radiation (e.g. WO/2000/049176), application of voltage (e.g. U.S. Pat. No. 5,527,670, U.S. Pat. No. 6,033,850, U.S. Pat. No. 5,939,291, and U.S. Pat. No. 6,333,157), and application of an electromagnetic field in combination with primers bound to a magnetically-responsive material (e.g. U.S. Pat. No. 5,545,540), which are hereby incorporated by reference in their entirety. In a variation called RT-PCR, reverse transcriptase (RT) is used to make a complementary DNA (cDNA) from RNA, and the cDNA is then amplified by PCR to produce multiple copies of DNA (e.g. U.S. Pat. No. 5,322,770 and U.S. Pat. No. 5,310,652, which are hereby incorporated by reference in their entirety).

One example of an isothermal amplification method is strand displacement amplification, commonly referred to as SDA, which uses cycles of annealing pairs of primer sequences to opposite strands of a target sequence, primer extension in the presence of a dNTP to produce a duplex hemiphosphorothioated primer extension product, endonuclease-mediated nicking of a hemimodified restriction endonuclease recognition site, and polymerase-mediated primer extension from the 3′ end of the nick to displace an existing strand and produce a strand for the next round of primer annealing, nicking and strand displacement, resulting in geometric amplification of product (e.g. U.S. Pat. No. 5,270,184 and U.S. Pat. No. 5,455,166, which are hereby incorporated by reference in their entirety). Thermophilic SDA (tSDA) uses thermophilic endonucleases and polymerases at higher temperatures in essentially the same method (European Pat. No. 0 684 315, which is hereby incorporated by reference in its entirety).

Other amplification methods include rolling circle amplification (RCA) (e.g., Lizardi, “Rolling Circle Replication Reporter Systems,” U.S. Pat. No. 5,854,033); helicase dependent amplification (HDA) (e.g., Kong et al., “Helicase Dependent Amplification Nucleic Acids,” U.S. Pat. Appln. Pub. No. US 2004-0058378 A1); and loop-mediated isothermal amplification (LAMP) (e.g., Notomi et al., “Process for Synthesizing Nucleic Acid,” U.S. Pat. No. 6,410,278), which are hereby incorporated by reference in their entirety. In some cases, isothermal amplification utilizes transcription by an RNA polymerase from a promoter sequence, such as may be incorporated into an oligonucleotide primer. Transcription-based amplification methods commonly used in the art include nucleic acid sequence based amplification, also referred to as NASBA (e.g. U.S. Pat. No. 5,130,238); methods which rely on the use of an RNA replicase to amplify the probe molecule itself, commonly referred to as Qβ replicase (e.g., Lizardi, P. et al. (1988) BioTechnol. 6, 1197-1202); self-sustained sequence replication (e.g., Guatelli, J. et al. (1990) Proc. Natl. Acad. Sci. USA 87, 1874-1878; Landgren (1993) Trends in Genetics 9, 199-202; and HELEN H. LEE et al., NUCLEIC ACID AMPLIFICATION TECHNOLOGIES (1997)); and methods for generating additional transcription templates (e.g. U.S. Pat. No. 5,480,784 and U.S. Pat. No. 5,399,491), which are hereby incorporated by reference in their entirety. Further methods of isothermal nucleic acid amplification include the use of primers containing non-canonical nucleotides (e.g. uracil or RNA nucleotides) in combination with an enzyme that cleaves nucleic acids at the non-canonical nucleotides (e.g. DNA glycosylase or RNaseH) to expose binding sites for additional primers (e.g. U.S. Pat. No. 6,251,639, U.S. Pat. No. 6,946,251, and U.S. Pat. No. 7,824,890), which are hereby incorporated by reference in their entirety. Isothermal amplification processes can be linear or exponential.

Nucleic acid amplification for subject identification may comprise sequential, parallel, or simultaneous amplification of a plurality of nucleic acid sequences, such as about, less than about, or more than about 10, 11, 12, 13, 14, 15, 20, 25, 30, 35, 40, 50, 100, or more target sequences. In some embodiments, a subjects entire genome or entire transcriptome is non-specifically amplified, the products of which are probed for one or more identifying sequence characteristics. An identifying sequence characteristic includes any feature of a nucleic acid sequence that can serve as a basis of differentiation between individuals. In some embodiments, an individual is uniquely identified to a selected statistical significance using about, less than about, or more than about 10, 11, 12, 13, 14, 15, 20, 25, 30, 35, 40, 50, 100, or more identifying sequences. In some embodiments, the statistical significance is about, or smaller than about 10⁻², 10⁻³, 10⁻⁴, 10⁻⁵, 10⁻⁶, 10⁻⁷, 10⁻⁸, 10⁻⁹, 10⁻¹⁰, 10⁻¹¹, 10⁻¹², 10⁻¹³, 10⁻¹⁴, 10⁻¹⁵, or smaller. Examples of identifying sequences include Restriction Fragment Length Polymorphisms (RFLP; Botstein, et al., Am. J. Hum. Genet. 32: 314-331, 1980; WO 90/13668), Single Nucleotide Polymorphisms (SNPs; Kwok, et al., Genomics 31: 123-126, 1996), Randomly Amplified Polymorphic DNA (RAPD; Williams, et al., Nucl. Acids Res. 18: 6531-6535, 1990), Simple Sequence Repeats (SSRs; Zhao & Kochert, Plant Mol. Biol. 21: 607-614, 1993; Zietkiewicz, et al. Genomics 20: 176-183, 1989), Amplified Fragment Length Polymorphisms (AFLP; Vos, et al., Nucl. Acids Res. 21: 4407-4414, 1995), Short Tandem Repeats (STRs), Variable Number of Tandem Repeats (VNTR), microsatellites (Tautz, Nucl. Acids. Res. 17: 6463-6471, 1989; Weber and May, Am. J. Hum. Genet. 44: 388-396, 1989), Inter-Retrotransposon Amplified Polymorphism (IRAP), Long Interspersed Elements (LINE), Long Tandem Repeats (LTR), Mobile Elements (ME), Retrotransposon Microsatellite Amplified Polymorphisms (REMAP), Retrotransposon-Based Insertion Polymorphisms (RBIP), Short Interspersed Elements (SINE), and Sequence Specific Amplified Polymorphism (SSAP). Additional examples of identifying sequences are known in the art, for example in US20030170705, which is incorporated herein by reference. A genetic signature may consist of multiple identifying sequences of a single type (e.g. SNPs), or may comprise a combination of two or more different types of identifying sequences in any number or combination.

Genetic signatures can be used in any process requiring the identification of one or more subjects, such as in paternity or maternity testing, in immigration and inheritance disputes, in breeding tests in animals, in zygosity testing in twins, in tests for inbreeding in humans and animals; in evaluation of transplant suitability such as with bone marrow transplants; in identification of human and animal remains; in quality control of cultured cells; in forensic testing such as forensic analysis of semen samples, blood stains, and other biological materials; in characterization of the genetic makeup of a tumor by testing for loss of heterozygosity; and in determining the allelic frequency of a particular identifying sequence. Samples useful in the generation of a genetics signature include evidence from a crime scene, blood, blood stains, semen, semen stains, bone, teeth, hair, saliva, urine, feces, fingernails, muscle or other soft tissue, cigarettes, stamps, envelopes, dandruff, fingerprints, items containing any of these, and combinations thereof. In some embodiments, two or more genetic signatures are generated and compared. In some embodiments, one or more genetics signatures are compared to one or more known genetic signatures, such as genetic signatures contained in a database.

A system may also verify whether the subject has received instruction to undergo a clinical test from a health care professional. The system may thus verify whether a subject has received an order from a health care professional to undertake a qualitative and/or quantitative evaluation of a biological sample. For example, the system may verify whether the subject has received a prescription from the health care professional to take the test. The system may verify whether the subject has received instructions from the health care professional to provide a sample to the device. The system may also verify whether the subject was authorized to go to a particular point of service to undergo the test. The verification may occur with aid of the device. The verification may occur at any time. In one example, the subject's authorization to take the test may be verified prior to preparing the subject's sample for the test. The subject's authorization to take the test may be verified prior to providing a sample to the device and/or cartridge. The verification of the subject's authorization may be provided after verifying the subject's identification. The verification of the subject's authorization may be provided before or after verifying the subject has insurance coverage for the clinical test. The system may verify whether the subject is covered by health insurance for a qualitative and/or quantitative evaluation of a sample, within the verifying step is performed prior to, concurrently with, or after processing a biological sample with the aid of a device, or transmitting the data from the device. The verification may take place through communications with the medical care provider, laboratory, payer, laboratory benefits manager, or any other entity. Verification may occur rapidly and/or in real-time. For example, verification may occur within 10 minutes or less, 5 minutes or less, 3 minutes or less, 1 minute or less, 45 seconds or less, 30 seconds or less, 20 seconds or less, 15 seconds or less, 10 seconds or less, 5 seconds or less, 3 seconds or less, 1 second or less, 0.5 seconds or less, or 0.1 seconds or less. The verification may be automated without requiring any human intervention.

The system may also verify whether the subject has insurance coverage for the clinical test. The system may verify whether the subject has insurance coverage to provide a sample to the device. The system may also verify whether the subject has insurance coverage for going to the point of service and undergoing the test. The verification may occur at any time. In one example, the subject's insurance coverage may be verified prior to preparing the subject's sample for the test. The subject's insurance coverage may be verified prior to providing a sample to the device and/or cartridge. The verification of the subject's insurance coverage may be provided after verifying the subject's identification. The verification of the subject's insurance coverage may be provided before or after verifying the subject has received a prescription to take the clinical test. The verification may take place through communications with the medical care provider, laboratory, payer, laboratory benefits manager, or any other entity. The verification may occur with the aid of the device. Verification may occur rapidly and/or in real-time. For example, verification may occur within 10 minutes or less, 5 minutes or less, 3 minutes or less, 1 minute or less, 45 seconds or less, 30 seconds or less, 20 seconds or less, 15 seconds or less, 10 seconds or less, 5 seconds or less, 3 seconds or less, 1 second or less, 0.5 seconds or less, or 0.1 seconds or less. The verification may be automated without requiring any human intervention.

The system may also verify whether the clinical test is appropriate for the subject. The system may verify whether an order for a qualitative and/or quantitative evaluation is within a set of policy restrictions. Such policy restrictions may form guidelines. Such policy restrictions may be policy restriction of a payer, prescribing physician or other ordering health care professional, laboratory, governmental or regulatory body, or any other entity. Such verification may depend on one or more known characteristic of the subject including but not limited to gender, age, or past medical history. A clinical decision support system may be provided. The system may be capable of accessing one or more medical records, or information associated with the subject. The system may be able to access records relating to the identity of the subject, insurance coverage of the subject, past and present medical treatments of the subject, biological features of the subject, and/or prescriptions provided to the subject. The system may be able to access electronic health records and/or pull up patient records and history. The system may also be able to pull up payer records, such as insurance and financial information relating to the subject. The verification may occur with the aid of the device.

In some embodiments, prior to providing a qualitative and/or quantitative evaluation, the system may be capable of accessing one or more records database and/or payer database. In some instances, the system may be capable of determining which records database and/or payer database to access prior to providing said qualitative and/or quantitative evaluation, and/or prior to accessing said databases. The system may make such determination based on the subject's identity, the subject's payer information, information collected about the sample, the proposed qualitative and/or quantitative evaluation, and/or any other information.

In one example, an inappropriate test may be a pregnancy test for a male subject or a PSA level (prostrate-specific antigen) for a female subject. Such tests may fall outside the policy restrictions of a payer or prescribing physician. Such ordering errors may be detectable by reviewing the test ordered and information associated with the subject. Such information associated with the subject may include medical records for the subject or identifying information about the subject. In one example, the appropriateness of the test is verified prior to preparing the subject's sample for the test. The subject's test appropriateness may be verified prior to, concurrently with, or subsequent to providing a sample to the device and/or cartridge. The verification of the subject's test appropriateness may be provided after or prior to verifying the subject's identification and/or insurance coverage. The verification may take place through communications with the medical care provider, laboratory, payer, laboratory benefits manager, or any other entity. A clinical decision support system may operate rapidly and/or in real-time. For example, verification may occur within 10 minutes or less, 5 minutes or less, 3 minutes or less, 1 minute or less, 45 seconds or less, 30 seconds or less, 20 seconds or less, 15 seconds or less, 10 seconds or less, 5 seconds or less, 3 seconds or less, 1 second or less, 0.5 seconds or less, or 0.1 seconds or less. The clinical decision support system may be automated without requiring any human intervention.

In some embodiments, qualified personnel may assist with collecting the subject's identity and/or providing a sample from the subject to the device. The qualified personnel may be an authorized technician that has been trained to use the device. The qualified personnel may be a designated operator of the device. The qualified personnel may or may not be a health care professional. In some embodiments, the identity of the qualified personnel may be verified. The qualified personnel's identity may be verified prior to, currently with, or after receiving the biological sample, transmitting the data from the device electronically and/or analyzing the transmitted data. The qualified personnel's identity may be verified prior to, currently with, or after verifying the identity of the subject. The qualified person's identity may be verified using one or more of the techniques described elsewhere herein.

FIG. 9 shows further examples of a system providing sample processing, analysis, and oversight. The numbers in the boxes in FIG. 9 have the same meanings as the corresponding numbers in FIG. 8. As shown in FIG. 9, arrows from the oversight box indicate that oversight may be oversight of analysis, oversight of communication over a network (such as the cloud, as exemplified by the cloud cartoon in the figure), and oversight of processing, e.g., oversight of the operation of a device processing a sample. As discussed above, oversight of operation of a device may be continuous oversight, e.g., during processing of a sample, and may include oversight in view of device information (including device identification, device status, device condition, and other device information), cartridge information, sample information, patient information, environmental information regarding a device, cartridge, sample, or other environmental information, and other information and data about or transmitted from a device. Such oversight may be oversight of oversight of analysis, oversight of communication, and oversight of processing, for each example in which oversight may be located at a laboratory location, or at a sample collection site. In embodiments, oversight may be located in the cloud or other network. In further embodiments, oversight includes oversight of post-analytic actions or steps.

Advantages of scenarios as illustrated in FIGS. 10A, 10B, 10C, and 10D, and as discussed herein, include providing a retailer with the ability to recognize revenue, e.g., upon receipt of payment. Such payment may be received from a customer, as shown in FIGS. 10A, 10B, 10C, and 10D; may be received from a laboratory, as shown in FIGS. 10A and 10B; or from a LBM, as shown in FIGS. 10C and 10D. As illustrated in the figure, a laboratory benefits manager (LBM) may communicate with, or be part of, a laboratory. (The dashed box around the boxes representing Laboratory and LBM, respectively, indicate that a laboratory and a LBM may be the same entity, or may be separate entities.) A test may be offered at a sample collection site, such as a retail site. The boxes labeled “Retailer” represent a sample collection site, which may be, for example, a store, another commercial location, a pharmacy, a health care facility, or other sample collection site. A customer, indicated by the boxes labeled “Customer”, may desire a service, such as a blood test, a urine test, or other test; the customer may pay a retailer for such a test; alternatively, a customer may pay only a portion of the amount owed for such a test (e.g., a copay). In embodiments, a customer does not pay the retailer, and the retailer receives payment from another party (e.g., a laboratory, a LBM, an insurance company, a health plan, a governmental agency, or other payer). A laboratory may provide services (e.g., may perform tests of a biological sample), may provide equipment, may provide disposables, and may do other acts for which payment may be expected. A laboratory or a LBM may send an invoice (e.g., a bill) to a payer requesting payment, as indicated by the arrow marked “Bill” in the figures. Dollar signs indicate payments. The head of the arrows indicates the directionality of the indicated action; for example, the upward-pointing arrow in FIG. 10A, labeled “Bill”, indicates that an LBM may bill a payer; and the downward-pointing arrow near the arrow labeled “Bill” indicates that a payer may provide a payment to the LBM. As shown, a laboratory may receive payments from a payer. A laboratory may provide payment or other moneys to a LBM. A laboratory may share payments or other moneys with a LBM. A LBM may receive payments from a payer. A LBM may provide payment or other moneys to a laboratory. A laboratory may share payments or other moneys with a LBM. In embodiments, a laboratory may provide information along with, separate from, or in addition to the payment or moneys, e.g., identification information, test information, insurance information, or other information. A LBM may manage payer relationships and contacts. A LBM may pay a retailer. For example, a LBM may reimburse a retailer an amount of money, e.g., according to a test that was performed. In embodiments, a laboratory may reimburse a retailer. A retailer may pay a fee or provide other payment to a LBM (e.g., may pay a service fee, an agent fee, or other fee). In embodiments, a laboratory or LBM may retain a fee from moneys paid by a retailer. In embodiments, a laboratory or LBM may retain a fee from moneys paid by a payer; in embodiments, a LBM may pay a fee to a laboratory. A laboratory may be an authorized laboratory, and may be a CLIA-compliant or CLIA-certified laboratory.

As indicated by the dashed boxes, a laboratory and a LBM may be the same entity, or may be separate entities. In addition, a laboratory may be a wholesaler, i.e., may provide equipment, supplies, etc. (e.g., devices, cartridges, and other materials useful for the practice of the methods disclosed herein, and for obtaining the devices and systems as disclosed herein). In embodiments, such items may be provided by third parties that need not be a laboratory.

As indicated in FIG. 10A, a customer may deal directly with a retailer, and may provide payment to a retailer. A retailer may deal with a laboratory, and pay, or pass payment to a laboratory (e.g., for services, equipment, materials, or other payments); the laboratory may pay a retailer (e.g., a fee). A laboratory may deal with a LBM, and payments (including fees, reimbursements, or other payments) may pass in either or both directions between a LBM and a laboratory. A LBM may deal with a payer (e.g., a health plan, insurance company, governmental agency, or other payer) by, for example, billing the payer for services (e.g., for the service provided to the customer) or for other costs or billable actions. A payer may pay a LBM per such a bill. In embodiments, a LBM and a laboratory may be the same entity, in which case the payer and the retailer deal with that entity.

As indicated in FIG. 10B, a customer may deal directly with a retailer, and may provide payment to a retailer. A retailer may deal with a laboratory, and pay, or pass payment to a laboratory (e.g., for services, equipment, materials, or other payments); the laboratory may pay a retailer (e.g., a fee). A laboratory may deal with a LBM, and payments (including fees, reimbursements, or other payments) may pass in either or both directions between a LBM and a laboratory. A laboratory may deal with a payer (e.g., a health plan, insurance company, governmental agency, or other payer) by, for example, billing the payer for services (e.g., for the service provided to the customer) or for other costs or billable actions. A payer may pay a laboratory per such a bill. In the scenario illustrated in FIG. 10B, the LBM does not deal directly with the payer, and the retailer does not deal directly with the LBM. In embodiments, a LBM and a laboratory may be the same entity, in which case the payer and the retailer deal with that entity.
